Why Did Puerto Rico's Economy Collapse?
Puerto Rico's economy collapsed due to a perfect storm of bad policy, political mismanagement, and economic dependency. The short answer: the U.S. Congress handed Puerto Rico a powerful economic lifeline in the form of tax incentives, allowed the island to build its entire economy around those incentives for decades, then abruptly pulled the plug — leaving the Commonwealth with no backup plan, a bloated government, and a rapidly growing debt. What followed was one of the most dramatic economic declines in modern American history.
Between 1980 and 2030, the U.S. state of South Carolina — which had roughly the same population as Puerto Rico in 1980 — added roughly two million new residents. Puerto Rico added just 2,705. That's a net increase of 0.08%, or about 61 people per year. Understanding why requires going back decades, to a postwar experiment that changed everything.
What Was Section 936 and Why Did It Matter?
By the late 1940s, Puerto Rico had been a U.S. territory for nearly half a century, yet its economy remained almost entirely driven by agriculture — dominated by sugarcane plantations and little else. During the Cold War, with Communist Cuba fewer than 500 miles away, Washington had strong ideological reasons to modernize its Caribbean outpost. The result was Operation Bootstrap — a sweeping campaign to transform Puerto Rico into a modern, export-oriented industrial economy.
The centerpiece of that campaign was Section 936 of the U.S. tax code. Section 936 reduced the federal income tax rate to zero on profits earned in Puerto Rico. At a time when U.S. corporations were just beginning to experiment with offshoring, this was extraordinary. Puerto Rico offered cheap labor, generous tax breaks, and direct access to the American market — all within U.S. territory. No tariffs. No trade restrictions. No foreign customs complications.
The policy proved especially attractive to one industry: Big Pharma. Pharmaceutical companies are uniquely suited to tax-sheltering strategies because the value of a drug is almost entirely tied to its patents — and patents, as abstract legal property, can be moved anywhere on earth overnight. A company like Pfizer could transfer its intellectual property to a Puerto Rican subsidiary, then argue that when someone in California bought Lipitor, 90% of the sale price was attributable to those patents — shifting that income to the island and making it tax-free. As a bonus, drug manufacturing itself is relatively cheap once a product is approved. By 1990, 17 of the top 21 most prescribed drugs in the United States were manufactured in Puerto Rico.
Why Did Big Pharma Abandon Puerto Rico?
Section 936 was always vulnerable — it had been created by Congress, and Congress could take it away. By the mid-1990s, the Cold War was over, Puerto Rico had lost its strategic significance, and lawmakers were focused on deficit reduction. The math was damning: for every single employee a pharmaceutical company hired in Puerto Rico, it saved an estimated $70,000 in taxes. In other words, the U.S. government was effectively paying $70,000 to employ one person in a place where per capita GDP was around $9,000.
Rather than reform Section 936 — say, by creating smarter incentives that required deeper local investment — Congress simply deleted it from the tax code entirely. Section 936 was phased out starting in 1996 and fully eliminated in 2006. Almost immediately, companies relocated to Ireland, Mexico, China, and elsewhere. And to worsen the blow, Puerto Rico had also lost its trade advantage: the rise of NAFTA, China's entry into the WTO, and a wave of bilateral trade agreements had eliminated the tariff privileges that once made the island uniquely attractive. Puerto Rico was no longer special. The manufacturing sector, which had once accounted for nearly 40% of GDP, began to hollow out. Then the Great Recession hit in 2008. By 2013, 230,000 out of 1.2 million total jobs had permanently disappeared.
How Did Puerto Rico's Debt Spiral Out of Control?
As revenues fell, Puerto Rico faced a painful choice: cut spending or borrow. It chose to borrow — and a quirk of its own constitution made that far too easy. Puerto Rico's constitution requires a balanced budget, but a mistranslation from the English original to the Spanish version changed the word "revenues" to "resources" — and in 1974, officials decided that borrowed funds counted as "resources." That interpretation opened the door to unlimited deficit spending with no real plan for repayment.
Rather than using borrowed money for investment — building infrastructure, attracting new industries — the government used it for everyday operating expenses: salaries, pensions, services. When old loans came due, it took out new ones to cover them. A U.S. government report later found that 16 out of every 20 bonds issued between 2000 and 2017 were used exclusively to repay or refinance existing debt. To fund this, Puerto Rico introduced a new sales tax in 2006 that eventually reached 11.5% — one of the highest in the United States — even as nearly half of its residents lived below the poverty line.
Investors kept buying Puerto Rican bonds for three reasons: the constitution prioritized bondholders in the event of default; the bonds were triple-tax exempt, meaning investors paid no city, state, or federal taxes on returns; and there was a widespread assumption that Washington would bail the island out if things got bad enough. That assumption collapsed in 2013, when Detroit filed for bankruptcy and the Obama administration declined to intervene. Puerto Rican bond ratings were downgraded to junk status. Interest rates spiked past 8%. The game was up.
In 2015, Puerto Rico's governor publicly admitted the island was trapped in a "death spiral." Its total debt stood at $73 billion — or $120 billion when unfunded pension obligations were included. Per capita, Puerto Rico owed fifteen times more than the median U.S. state. Detroit's infamous $18 billion bankruptcy, which had shocked the nation, looked modest by comparison.
Why Are So Many Puerto Ricans Leaving the Island?
When Congress and an unelected federal oversight board imposed austerity — cutting sick days, reducing pensions, rationing healthcare — they ran into a problem that doesn't exist in most debt crises: Puerto Ricans can leave. As U.S. citizens, they can live, work, and study anywhere on the American mainland without restriction. No visa. No passport. Just a one-way flight to Miami, Orlando, or New York.
And that's exactly what happened. Every year, between 50,000 and 100,000 people leave. Today, nearly twice as many self-identified Puerto Ricans live on the U.S. mainland as on the island itself. The economic consequences are severe: those most likely to leave are young, educated, and higher-earning — precisely the people any economy needs most. Puerto Rico's median age is now 43, older than every U.S. state except Maine. Fewer than half of its adults participate in the labor force.
The vicious cycle is self-reinforcing: as taxpayers leave, the burden on those who remain increases. Higher taxes and worse services push more people to leave. Which increases the burden further. And so on.
What Is Puerto Rico's Economic Crisis Today?
Puerto Rico today looks far less like its Caribbean neighbors — young, growing economies still developing — and far more like West Virginia: deindustrialized, depopulating, and struggling to find a new economic identity in a globalized world. Manufacturing is gone. The government is oversized relative to the tax base. And the population is aging rapidly with no clear engine of growth on the horizon.
The federal oversight board continues to hold veto power over the territory's budget, a condition that many Puerto Ricans view as a form of colonial governance. Hurricane Maria in 2017 added another devastating blow, wiping out infrastructure and accelerating emigration. Recovery funds have trickled in slowly, and corruption scandals have undermined public trust in the government's ability to deploy them effectively.
Can Puerto Rico Ever Recover From Its Crisis?
The honest answer is: it's very hard to see how. The core problem is a Gordian Knot with no clean solution. To slow the outmigration, Puerto Rico needs to improve economic conditions. To improve economic conditions, it needs to slow the outmigration. Neither can happen first. West Virginia, which is substantially wealthier and has more federal support, has still been unable to reverse its own population decline. Even China — with authoritarian control over its 1.4 billion citizens — has struggled to engineer demographic recovery after decades of population policy.
What Puerto Rico needed, perhaps, was a gradual and well-planned transition away from Section 936 — not an abrupt repeal. It needed smarter investment in local industry, better governance, and a debt structure that didn't let politicians mortgage the future for short-term political comfort. Instead, it got the worst of all worlds: a boom built on a single policy, a collapse when that policy ended, and a debt crisis that will take generations to unwind.
The story of Puerto Rico is ultimately a story about what happens when a place becomes economically dependent on forces entirely outside its control — and what the cost of that dependence looks like when those forces change.
