Capitalism is defined as a set of rules/regulations that allows people to own the capital that they produce. Regulatory capture is when an organization gains control of the regulations to subvert other people’s ability to own their capital. This is why I say that the more regulatory capture that happens, the less capitalist the system.
And yes! Capitalist systems heavily incentivize caring about money and nothing else. But the system also makes it so that when people act purely selfishly for money, that it results in good outcomes for everyone. That’s why I think it’s a good system.
For example, if organizations price-fix, it heavily encourages a third party to undercut them. If they try to prevent the third party by legal means, then that’s not capitalism.
