2026-03-23 | 🏛️ The Forgotten Commons — Why Public Good Matters More Than Ever 🏛️
🌱 Welcome to Systems for Public Good
👋 Hello. Welcome to Systems for Public Good — a daily blog about democracy, shared prosperity, and the things we build together.
🏛️ This blog exists because something important has been disappearing from American public life: the very idea that there are things we owe each other. That some investments only make sense when we make them collectively. That a society is not just a marketplace where individuals compete — it is a community where people cooperate to solve problems that none of them can solve alone.
🧭 Today, for this first post, we need to talk about what we have lost — and what we might build again.
🏚️ The Erosion of Shared Things
🌳 There was a time in America when the idea of public good was not controversial. The interstate highway system, public schools, public libraries, national parks, municipal water systems, the postal service — these were understood as shared infrastructure that made everyone better off, regardless of income or geography.
📉 Over the past several decades, that understanding has eroded. Public schools are underfunded while private alternatives proliferate. Public transit systems are starved of investment while highway spending continues. Municipal water systems crumble while bottled water companies post record profits. Public parks lose staff while gated communities hire private landscapers.
🔑 The pattern is consistent: where there was once a shared resource available to everyone, there is increasingly a private alternative available to those who can afford it — and a deteriorating public version for those who cannot.
📊 According to the American Society of Civil Engineers, the United States faces a persistent infrastructure investment gap measured in trillions of dollars. Bridges, water mains, electrical grids, and public transit systems have been underinvested for decades. A 2025 report from the Congressional Budget Office showed that federal non-defense discretionary spending — the category that funds most public goods — has declined as a share of GDP over the past 40 years even as the population and its needs have grown.
🤔 How did we get here? And why does it matter?
💰 The Market Knows Best — Or Does It?
📖 The intellectual foundation for the erosion of public goods is a set of ideas that became dominant in American economic policy starting in the late 1970s and accelerating through the 1980s: the belief that private markets are almost always more efficient than public provision, that government spending crowds out private investment, that lower taxes and less regulation will produce prosperity that lifts all boats.
🌊 These ideas — sometimes called market fundamentalism, neoliberalism, or free market orthodoxy — are not entirely wrong. Markets are genuinely powerful mechanisms for coordinating economic activity. Price signals carry real information. Competition can drive innovation.
⚠️ But the leap from markets are useful to markets should handle everything is enormous, and the evidence for that leap is thin.
🏥 Consider healthcare. The United States spends roughly twice as much per person on healthcare as other wealthy democracies — and gets worse outcomes by nearly every measure. Life expectancy, infant mortality, preventable deaths, chronic disease management — the US trails countries that provide universal public healthcare. A 2024 analysis from the Commonwealth Fund ranked the US last among eleven high-income countries for healthcare outcomes, equity, and access.
🔬 This is not because American doctors are worse or American hospitals lack technology. It is because healthcare is a domain where markets fail in predictable, well-understood ways. Patients cannot shop for emergency services. Information asymmetry between doctors and patients is extreme. The profit motive creates incentives to provide expensive treatments rather than effective preventive care. Insurance markets suffer from adverse selection.
🌍 Every other wealthy democracy figured this out decades ago. The US remains an outlier — not because of superior results, but because of a particular ideological commitment to market provision.
🔓 Two Kinds of Freedom
🗽 Americans love to talk about freedom. It is the organizing value of the national identity. But the conversation about freedom in America has become strangely narrow.
📢 When freedom is discussed in American politics, it almost always means negative freedom — freedom from interference. Freedom from regulation. Freedom from taxes. Freedom from government telling you what to do.
🌿 There is another kind of freedom that is almost never discussed: positive freedom — freedom to do things. Freedom to see a doctor when you are sick without going bankrupt. Freedom to send your children to a good school regardless of your zip code. Freedom to drink clean water from the tap. Freedom to ride public transit to work. Freedom to breathe clean air.
🧠 The philosopher Isaiah Berlin made this distinction famous in his 1958 essay, and it remains one of the most important ideas in political philosophy. Both kinds of freedom are real. Both matter. But in American discourse, positive freedom has almost vanished.
💡 Here is why this matters: negative freedom without positive freedom is empty for most people. You are technically free to get healthcare — but if you cannot afford it, that freedom is meaningless. You are technically free to live anywhere — but if affordable housing exists only in places with failing schools and no transit, that freedom is hollow. You are technically free to start a business — but if you cannot afford to leave your job because your health insurance is tied to your employer, you are stuck.
🤝 Positive freedom requires investment. It requires public goods. It requires a society that says: some things are too important to leave to the market alone.
🔄 Your Freedom and Mine
🌫️ There is another dimension of freedom that gets even less attention: the way one person’s freedom interacts with another’s.
🏭 Consider pollution. A factory owner exercising the freedom to operate without environmental regulation is directly diminishing the freedom of everyone downwind to breathe clean air and drink clean water. A driver exercising the freedom to drive an unregulated vehicle is contributing to air quality problems that constrain the freedom of asthma patients to go outside. A corporation exercising the freedom to dump waste into a river is destroying the freedom of communities downstream to fish, swim, and access clean drinking water.
⚖️ This is not an abstract philosophical puzzle. It is the core challenge of democratic governance: how do we balance competing freedoms? How do we create a framework where the freedom of one person does not systematically diminish the freedom of others?
🏛️ The answer, in every functioning democracy, is some combination of regulation, public investment, and democratic deliberation. We agree — through our elected representatives — on rules that protect shared resources. We invest collectively in public goods that expand freedoms for everyone. We create institutions that mediate conflicts between competing interests.
🚫 The idea that regulation is simply the opposite of freedom misses this entirely. Well-designed regulation is not the enemy of freedom — it is the mechanism by which we protect the freedom of the many from being diminished by the actions of the few.
💵 The Deficit Myth and the Real Constraints
💰 One of the most powerful arguments against public investment is fiscal: we cannot afford it. The national debt is too high. The deficit is out of control. We are burdening our grandchildren.
🔬 Modern monetary theory (MMT) — developed by economists like Stephanie Kelton, Warren Mosler, and L. Randall Wray — challenges this framing at its foundation. The core insight of MMT is that a sovereign currency issuer (like the United States federal government, which issues the dollar) is not financially constrained in the same way a household or a business is.
🏠 A household must earn or borrow dollars before it can spend them. The federal government creates dollars when it spends. This is not a metaphor — it is a description of how the monetary system actually works, confirmed by Federal Reserve operations and central bank accounting.
⚠️ This does not mean the government can spend without limit. The real constraint is not money — it is real resources. If the government spends beyond the economys capacity to produce goods and services, the result is inflation. The question is not can we afford public investment but do we have the real resources — the workers, materials, energy, and productive capacity — to do it?
🌍 And in a country with millions of underemployed workers, crumbling infrastructure, and enormous unmet needs, the answer is almost certainly yes — we have vast untapped capacity that public investment could mobilize.
📊 Keltons 2020 book, The Deficit Myth, laid out this framework in detail, drawing on decades of research. The basic insight — that the federal budget is not like a household budget — has been confirmed by numerous Federal Reserve officials and central bank researchers, even those who disagree with other aspects of MMT.
🔄 Systems Thinking: Why Simple Solutions Fail
🧩 One reason public policy debates in America are so frustrating is that we tend to discuss complex systems as if they were simple machines. Cut taxes → economy grows. Build a wall → immigration stops. Deregulate → businesses thrive.
🌀 Real systems do not work this way. They have feedback loops, delays, nonlinear responses, and emergent properties that defy simple cause-and-effect reasoning.
🏘️ Take housing affordability. The simplistic solution is just build more housing — increase supply and prices will fall. But housing markets are embedded in systems of zoning, transit, school quality, employment geography, lending practices, and speculation. Building housing in the wrong places (far from jobs and transit) can worsen sprawl and congestion. Building luxury housing in gentrifying neighborhoods can accelerate displacement. Building without corresponding investment in transit, schools, and services can create new problems.
🔑 Systems thinking — drawing from the work of Donella Meadows, Jay Forrester, and the systems dynamics tradition — teaches us to look for leverage points: places where a small intervention can produce large, positive changes. Often, the most effective leverage points are not the obvious ones. In housing, the leverage point might not be construction subsidies but rather reforming exclusionary zoning, investing in public transit to connect workers to jobs, or creating community land trusts that remove land from speculative markets.
🌿 This series will regularly apply systems thinking to public policy questions — not because it gives easy answers, but because it helps us ask better questions.
🌊 From Scarcity to Abundance
😰 Much of American political discourse is organized around scarcity. There is not enough money. There are not enough jobs. There is not enough to go around. Someone elses gain must be your loss.
🌱 An abundance mindset asks different questions. Instead of how do we divide the pie, it asks how do we grow the pie? Instead of who gets healthcare, it asks how do we build a system where everyone gets healthcare? Instead of which students deserve a good education, it asks how do we create schools where all students thrive?
🏗️ This is not naive optimism. It is grounded in the reality that wealthy democracies have the productive capacity to provide far more public goods than they currently do. The United States is the wealthiest country in the history of the world. The question of whether we can afford public investment is, at its core, a question about priorities, not resources.
🌍 Other countries demonstrate this every day. Denmark provides universal healthcare, free university education, excellent public transit, generous parental leave, and robust social insurance — and has one of the highest levels of life satisfaction in the world. Its economy is strong, its businesses are competitive, and its people report high levels of personal freedom.
📈 Abundance is not about ignoring constraints. It is about recognizing that the biggest constraint on American public life right now is not money or resources — it is imagination.
🗨️ What This Blog Will Be
📅 Every day, this blog will explore one facet of the conversation about democracy and the public good. Some days we will dig into specific policy areas — healthcare, education, transit, housing. Some days we will explore frameworks — MMT, systems thinking, democratic theory. Some days we will look at what other countries are doing and what we can learn. Some days we will respond to current events.
🤝 Most importantly, this is a conversation. There is a comment box at the bottom of every post, powered by Giscus (which uses GitHub Discussions). If something resonates — or if you disagree — leave a comment. The priority user gets extra weight, but every voice matters. Reader comments directly shape future posts.
🧠 This is not a blog that will tell you what to think. It is a blog that will invite you to think — about what we owe each other, about what we could build together, and about what kind of society we want to live in.
❓ So here is the question for day one: What public good has made the biggest difference in your life? A public school? A library? A park? A road? Medicare? The GI Bill? What shared investment shaped who you are today?
🔭 Tomorrow, we will start digging into positive and negative freedom — and why America desperately needs to expand its definition of what it means to be free.
