It controlled the mines of the Americas. It extracted so much silver it tripled Europe’s entire silver supply. The Spanish empire was the wealthiest on the planet.
Within two centuries, Spain was one of the poorer nations in Europe.
Thomas Sowell spent fifteen years researching why — and what he found has direct implications for how you protect your savings today.

The Spain Lesson Nobody Teaches
In Conquests and Cultures, Sowell documented the Spanish extraction of precious metals from the Americas with the analytical precision that defined his career.
The Spanish hauled out staggering quantities of silver and gold. They flooded European markets with it. And in doing so they triggered massive inflation across the continent — prices for ordinary goods doubled and tripled in some regions over the course of a century as the money supply expanded far faster than the actual production of things people needed.
Then the mines declined.
When the flow of metal slowed, Spain had nothing to fall back on. It had not built productive institutions. It had not developed manufacturing capacity. It had not cultivated the kind of market-oriented economic culture that generates lasting wealth through innovation, trade, and voluntary exchange.
It had extracted. It had not produced.
And once there was nothing left to extract, the empire began to unravel.
What Sowell Was Actually Arguing
The standard historical narrative about Spain and the Americas focuses on exploitation — on the moral dimensions of what was taken from indigenous peoples.
Sowell did not ignore that. But he asked the economic question that historians rarely ask.
If Spain got all the gold, why did it end up poor?
His answer cuts through centuries of accepted wisdom.
Looted wealth does not produce lasting prosperity. What produces lasting prosperity is the institutional capacity to generate wealth through productive activity — through markets, incentives, rule of law, and the kind of voluntary exchange that creates value rather than simply redistributing it.
Spain got the metal. The Dutch and the English got the institutions. And over the long run of history, institutions won decisively.
This is not a history lesson. It is an economic principle that explains what is happening right now.
What This Has to Do With Your Savings
Here is the connection Sowell would draw.
The US dollar has functioned for decades as the world’s reserve currency — the closest modern equivalent to the Spanish silver that once dominated global trade. Countries held dollars because they trusted what dollars represented. That trust was the institutional foundation that made the dollar valuable.
But Sowell’s framework asks what happens when the institution deteriorates.
The national debt is approaching $40 trillion. The government is adding to that debt at a pace that would have been unthinkable a generation ago. The Federal Reserve has a stated policy of 2 percent annual inflation — a deliberate, designed erosion of the currency’s purchasing power. The personal savings rate just hit one of its lowest levels in 65 years, meaning ordinary Americans are losing ground in real terms even as their nominal incomes rise.
Spain thought it had won because it had the gold. The people who actually built lasting wealth understood that gold is not wealth — productive capacity is wealth. Institutions are wealth. The ability to generate value rather than simply hold a metal is wealth.
But here is the other side of that argument.
When the institutions start to fail — when the currency starts to erode, when the government starts to spend beyond what any productive economy can sustain, when the political system has every incentive to inflate rather than reform — holding something outside that system becomes the rational response.
Not because gold is wealth in itself.
Because everything denominated in a deteriorating currency is losing ground against something that cannot be inflated.
Sowell’s Broader Lesson for 2026
Sowell spent decades arguing that free markets, sound institutions, and productive incentives create lasting prosperity. He was right about that.
He spent equal time documenting what happens when governments try to shortcut that process — through redistribution, through monetary manipulation, through the illusion that controlling money is the same as creating value.
Spain thought controlling the silver supply made it powerful.
The Federal Reserve thinks controlling the money supply makes the economy stable.
Sowell’s fifteen years of research across civilizations suggests both were wrong about the same thing — that you cannot substitute control over money for the productive capacity that actually generates wealth.
For people whose savings are concentrated in a currency being deliberately managed toward inflation, the practical question is not whether to trust the system.
The practical question is what to hold when the system does to your dollars what Spain’s mines eventually did to its empire.
