Something is going to break real soon. Either they're going to have to scrap income tax altogether or raise the rates, especially on high income earners. That's not going to make very many people happy. Trump gave everyone, especially high income earners' a tax cut but that just raised our debt to 24 trillion. If you don't think that's an issue, what for the next budget appropriations fight in congress and they shut down the fed gov't .......again.
Income tax is a bad idea. Lots of people with income, like those who are self employed, don't pay it. They work on a cash basis. I've hired a few.
Those that pay no income tax would prefer the 1K/mo. That alone would make me favor the no-more-income-tax plan. Everyone would then be playing on a level field. The fed could then raise the consumption tax on fuel, tobacco, alcohol, airline tickets etc. Wouldn't break my heart. At least the free loaders would be paying something.
