This is the problem with a flat tax. If we had a flat 20% tax on income for someone who makes 50k a year, that is 10k and leaves them with only 40k. For someone who makes 5M a year that is 1M but still leaves them with 4M.
Losing that 10k when you only had 50k to start with matters a lot. Losing that 1M isn’t a big deal when you still have 4M left!
