A very intelgent question void of political bias (rare these days on HN). Thank you for that! My other alternative suggestion to a flat income tax is a progressive sales tax based on what you want to incentivize. Gas guzzlers? First class flight? Tax the shit out of them. Solar roof? Basic groceries? No tax. Used/preowned goods? Zero tax (a loophole for opting out). Etc.
