Why wait for a tax? If we're in the top %x of income earners, why aren't we taking it upon ourselves to give away our wealth? Form a charitable organization that takes care of people, donate your money.

Edit: I'm with the others here replying with "reduced burdens on the middle class and small businesses" and "...teach a man to fish..." I keep seeing this basic income and wealth distribution topic on HN and I would genuinely like to understand why those preaching for these ideas never actually do anything about it. "Make the government bigger" isn't the answer as it'll then be used as a tool of oppression.

Further, assuming we implemented a basic income in the USA, how many generations until the motivators for innovation and advancing society are completely eliminated? I've everything I need at $BASIC_INCOME, and as soon as I start producing more income, the government is stripping it from me, so what's my motivation to ever do anything besides subsist on that minimum? And once everyone is just taking the minimum and not doing work, who's gonna farm the food? Drive the trucks? Operate a grocery? Build the houses?
