Inglewood and Santa Monica are close enough to require the same level of income in order to afford a certain standard of living. Sure the standards of living may not overlap much, but they are on the same scale.
That's not true of California and Ohio in general.
Regardless of Ohio or California: you're saying that companies should pay less based on the income of their neighbourhood and you don't agree that it will disproportionately affect people of colour.
Interesting perspective, I don’t think I agree though.
Not income of their neighbourhood, but the cost of living in their city/state. It needs to be a big enough region that a good job gives social mobility, but introducing California wages into Ohio would cause massive inflation there, driving normal people into poverty. At the same time nobody could live in LA on Ohio wages.
