This person is missing the point of wealth. Wealth isn't about the number of dollars. It doesn't matter that the wealth of all the billionaires combined is less than what the government spends in a year. The problem is that when someone has enough wealth they gain the ability to control society. They have their hand on the levers of power, and there is no democratic input into how they pull or push those levers. Forget about socialism and capitalism. If you believe in democracy, then no person who isn't an elected representative can be permitted to accumulate enough power to make decisions that impact all of society in any significant way. That is why there should be something along the lines of a wealth cap, wealth tax, or whatever other policy you want to implement to make sure that doesn't happen.
