Often our critiques of capitalism are not critiques of capitalism at all. In fact they’re criticisms of monopolies and oligopolies in our modern society, which are antithetic to capitalism.
The American economy is an aristocracy. VCs, the big ones at least, are members of that aristocracy. Many of which are filled with smart good hearted people. But there are some incentives baked into their position of power that we need to be cognizant of.
Edit: “free-market capitalism” would probably have been a better term. Clearly that was not the point I was making.
