In my experience, most self-proclaimed "capitalists" either lap up the scholastic propaganda that capitalism is the 'bestest' economic system in the world, or are a real capitalist and don't have to give one fuck about what others say.

And most of these types NEVER read past, say, page 20 of https://www.gutenberg.org/files/38194/38194-h/38194-h.htm , Adam Smiths treatise on capitalism. Here's a few failures that Smith wrote back in his initial treatise in 1776. I think so far, we're failing every one of these, and basically speedrunning all the terrible warnings Smith wrote about as accomplishments.

Gross inequality was even mentioned there as something to significantly avoid. Book I, Ch. X, Part II; ~p. 50

Principal-agent problems in joint-stock companies. Managers of other people's money "cannot be expected to watch over it with the same anxious vigilance" as owners, leading to waste and negligence. Book V, Ch. I, Part III; ~p. 312-313

Mercantilist policy distortions. Protectionism, export bounties, and import restrictions enrich narrow merchant interests while reducing national wealth by intentionally misallocating capital. Book IV, Ch. II-V; ~p. 183-213

Underprovision of public goods. Markets fail to supply infrastructure (roads, bridges, canals, harbors) and institutions that benefit society broadly but yield no direct profit to private actors. Book V, Ch. I, Part III, Art. I; ~p. 303-305. https://www.independent.co.uk/news/world/americas/us-cities-...

Dehumanizing effects of extreme division of labor. Repetitive specialized labor "renders [the worker] as stupid and ignorant as it is possible for a human creature to become," impairing civic and moral capacities. Book V, Ch. I, Part III, Art. II; ~p. 324 . Even in the 1800's this got so bad that Karl Marx wrote about this in both of his critique of capitalism AND the communist manifesto.

Merchant collusion and monopoly power. Smith warns that "people of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices". Book I, Ch. X, Part II; ~p. 54 . Hello, eggs, meat packers,oil products (gasoline), grocery chains, electronics (RAM), health care. Collusion after collusion, and almost no enforcement.

Im not communist, and probably not socialist. But its clear as day as to the failures of capitalism. And as a stopped clock is right 2x a day, capitalism does handle some problems better than any previous system. But we can do better. Lots better. But the entrenched power holds on to capitalism as fervent as a religion, and not dispassionate analysis.
