Economics, as a science, has generally been used to measure and describe capitalist economies, since economics as a science has only existed as long as capitalism.

Which is fine.

Economics has had a bad habit of universalizing its descriptions of capitalist economies as if they were fundamental facts about human nature.

Which is not fine.

So, for example, economists talk about the “tragedy of the commons”, as if it was a law of nature that publicly owned resources are necessarily used to destruction by selfish individuals, and only private ownership enforced by law can prevent this destruction. When, in fact, publicly owned resources have been maintained by societies ever since society was a thing, the commons in England existed for thousands of years before capitalism was a gleam in Adam Smith’s eye, and the term itself was popularized by Garrett Hardin in 1968 as a justification for abolishing welfare and letting poor people starve.

But hey, our colonial ancestors took millions and millions of acres of “unowned” land from native peoples, auctioned it off to private landowners, and turned the native people into slave labor to farm it, and isn’t it nice to tell ourselves that we’re using that land more efficiently and protecting it from overuse and mismanagement by privatizing it?

I mean, look, if I said to you “making profit is the highest good, and it is morally right for me to use every legal method at my disposal to make as much profit as I can from you”, you’d say I was evil or insane.

But if I said to you “making profit is the most important goal of my business, and it is morally right for me to use every legal method to make as much money as I can from customers” you’d probably nod and smile and agree.

And that’s the corrupting influence of economics, which has confused efficiency and morality so greatly that it’s convinced us that capitalism is the most moral form of social organization because a capitalist economy is the most efficient form of economic organization. Neither of which is true.

And this ties into fascism, and dictatorships, and Belgians in the Congo, and all sorts of monstrous human rights violations in the name of profit, because monstrous human rights violations naturally occur when you reduce human beings to commodities and tell yourself the highest form of morality lies in using those commodities as efficiently and profitably as you can.

Economics is not exclusively used for fascism, sure, but it’s done more to promote fascism than any other single science I can think of.
