Local governments are also involved in the stock market. High frequency traders make money by acting as an intermediary between buyers and sellers, and thus not creating actual wealth. Instead their supposed value is the "liquidity" they add. That means that the price of "adding liquidity" is a lower return on a stock or bond invested by a local government. Which in turn means that the local government might have to cut funding services for the poor. Even if you give away the money you earn, you are still robbing the poor so you can give to the poor people that you like.
