The problem is that tax deductions/credits are a useful tool for guiding certain activity. We want people to put up solar panels, so we give a tax credit for that.
The other argument for a progressive system is using money for necessities instead of luxuries or investment. Your first $40k or $50k or so is spent on the basic cost of living. After that, you’re using increasing amounts for things you don’t strictly need. So you want to tax that first $50k or so very little, perhaps none at all, and then ramp it up on the people who are just spending money on fast cars or dumping it into SPY or whatever.
There’s a ton of twisty little ways the tax system makes everything fair-ish. Turns out, running a country of 330M people and an annual GDP of $25T is complicated. It’s not always a fair system, but it’s more fair than it looks at first glance.
