Thank you for coming to my Ted Talk
No, that's not what defines capitalism at all. That's a degenerate form more usually called "predatory capitalism".
In what was is predatory capitalism not the rule of the day?
I don't see where the logic of your comment comes from either way though - capitalists are typically in favour of a free market, no? And typically the "purpose" of a free market is accruing wealth as part of a private enterprise?
That's why we see so many mergers and intensive lobbying for government regulation in things like healthcare, telecoms, and air travel, it's way easier to make money if you can restrict competition in your market and it's something essential to consumers
E.g.: Democracy, oligarchy, dictatorships are forms of government.
Capitalism, socialism, etc... are economic systems.
I point this out because people in my country sometimes forget that it's a system of elected officials that govern us, not capitalism.
