Progressive taxation of someone earning $100k per year in San Francisco or NYC is hardly fair. At least prior to covid19 causing a crash in the rental market one could expect to pay ~$2500 a month to share a 2bedroom place. That's spending 42% of take home pay to have roommates! Not to mention everything else costs more, a meal out, riding the bus, getting your bicycle repaired, clothing etc.
$400k per year is about what it takes to run a middle class family w/ 2 kids in such a city. -- They're already paying $162,121 in taxes annually.
When we progressively tax those who actually have less than the median after CoL, we're being unfair (IMO)
