alt Hacker News> would a flat tax (which is nominally regressive) actually be more progressive than the regressive taxes we have?
That's an easy one to fix regardless. Use a flat tax with a large fixed refundable credit. Now everyone pays e.g. 30% but gets a $12,000 credit, so someone who makes $40,000 is effectively paying zero, someone who makes $80,000 is effectively paying 15% and the effective rate approaches 30% as the number goes up. But the marginal rate is the same for everyone so there aren't all these complexities and arbitrage games, and at lower incomes the credit stands in for a lot of assistance programs so you don't get all the marginal rate cliffs from overlapping phase outs.

This only maybe works if you count capital gains as regular income. Otherwise they do the Steve Jobs $1 salary thing.
Even the capital gains can be largely evaded. https://www.propublica.org/article/billionaires-tax-avoidanc... https://www.propublica.org/article/lord-of-the-roths-how-tec... etc.
