So fuck the middle class because the rich don't want to pay taxes?

There's a great deal of evidence that we actually save money by providing housing, shelters and other services to poor people. Unfortunately, the politics make this unpopular and dictate that when they are provided they come with strings attached that discourage their use. It really isn't a question of not wanting to pay taxes and much more question of demonizing poor people.

The money spent on policing, cleanup, and emergency medical care is often far more than we would spend if we would just fund helping lift people out of poverty without all the moralizing.

The middle class makes up most of the tax payer population. You can't tax income at the top and expect much unless you added 20%.

Your statement isn't incorrect, but it has missed the point. Yea the middle class will always bear the majority of the tax burden in absolute terms, but that doesn't mean it's silly to tax the rich, the take home is pretty minor but they should always be paying more money in absolute individual terms than the middle class - right now they usually pay less, sometimes they pay nothing, sometimes they get a handout.

Most of the tax payer population, but not most of the gains available for taxation. Small increases in taxes to the very wealthy would far outweigh large increases in taxes to the middle class in terms of government revenue.

On top of that, you say "unless you added 20%" as if that's something that's beyond the pale when in fact the wealthiest people pay far less in taxes that at any point in our country's history.

The top 1% in the US has absorbed nearly the entire economic growth for the last 30 years or so.

The number of people doesn’t really matter. It’s the percentage of wealth that they hold that matters.

Other segments of the population have seen absolutely no economic growth.

The top 1% isn't getting income via employment payroll.

They own entities globally and can afford to give themselves a dollar a year salary. If you are only raising employment income taxes you have to get it from the middle class.
