I agree that a well functioning market creates a lot of wealth for everyone and reduces poverty. There's innovation. There's cheaper and better stuff and services. I strongly support a mixed economy.
IDK why you keep saying it this way, but I am not for destroying wealth generators. Successful businesses who don't create billionaires also generate wealth. Billionaires don't prove the economy is good, but they are most easily able to use that wealth to thwart competition.
