I don't think anyone is against your examples. The issue is WHERE the tax money is coming from and the PROPORTIONS of tax paid in relation to overall income.

Unfortunately right now the middle class is being stuck with most of the bill on a PER-CAPITA income basis. And considering the wealth gap between the rich and the middle class is SUBSTANTIAL, it means we're essentially having relatively poor people (middle class) pay the bills of very poor people (lower class).

When you zoom out a little (and remove irrational emotions about the topic clouding your perception), it's easier to see the disconnect.
