The ones at the top and at the bottom aren't heavily impacted by taxes. The middle classes are. The government protects the richest, because if regulators introduce tax policy against them, their wealth leaves the country immediately to a more friendly country which won't charge them at all... Meanwhile, the poors don't have much to contribute and heavily rely on welfare programs to survive, so the final burden is carried by the middle classes, who are the most prejudiced ones, since they want to work and thrive, but find many obstacles on the way, because the government sabotages them all the time through abusive taxes.
As far as I've seen, countries haven't managed to get rid of this vicious cycle yet. Here in my country, officially, around 40% of the yearly income of an average citizen returns to the government through taxes. That is insane, and for much less we already had armed revolts in a far historical past against the imperial government.
This is very correct, and unfortunately it is making middle class live like poor of the old days as well. If you are in the USA and making 40k a year, then you are poor, and you do not pay that much taxes and government doesn't "benefit" from you, if you are making a million dollars a month, you could protect it in a hundred different ways, but if you are someone who makes about 10k a month, which is 120k, you are not poor, but you are not "that" rich neither, so they tax you to hell, and you can't afford a decent house most of the time because of it.
I believe that we are going to end up with rich people eventually getting a bit more taxed, because the current system is not sustainable, and there won't be any other method left even if they want to avoid taxing the rich.
