Capitalism is when there's a state that only permits private property if operated as a small business that operates within strict boundaries. This capitalist state would prevent business owners from having too many employees, from owning businesses other than one, and business owners would be subject to taxation that other citizens aren't. This is to ensure no private business gains too much authority. Corporations of course, are illegal and so is owning anything in a stock market.

Also I'm describing Cuba. Their lack of an income tax except for people in the private sector is very, very funny and cool to me.
