That’s not the definition or foundation of capitalism, it’s the definition of a market economy.
The foundation of capitalism is a system where investors can pool small amounts of money together on big projects, to share risk and reward. Historically to fund trading ships on their way to the indies.
So it destructures ownership, which has a million ripple effects on the organization and economy.
Not at all, corporatism is a system where interest groups have a high amount of power : guilds, syndicates, unions, etc…
Capitalism literally refers to pooling capital together from multiple sources to allow shared risk taking and allow for the creation of companies that can get bigger by having more than one owner.
This eventually leads the way for pension funds and multinational corporations whose sole purpose is to extract maximum value for pensioners and billionaires.
