Republicans, or more specifically their wealthy puppet masters love taxes on the poor. That’s because while individuals might avoid doing business with them, you can’t avoid paying your taxes, and once the money is in the hands of the government they have all kinds of tricks to funnel it into their own pockets. Additionally it keeps the poor poor which makes them easier to exploit and turn into wage slaves that are so desperate for a job that they’ll put up with horrible working conditions. Lastly poor people have fewer opportunities for education which limits their job prospects and as a bonus makes them easier to manipulate using propaganda.
As long as they don’t have to pay it, they’ll gladly support taxes levied on other people, but the moment you ask them to pay a single cent in taxes they’ll bitch and moan about it.
