The 'basic' cost of living for everyone is more or less the same. It's a proportionally larger share of your income if you have less money. $250K is a high wage relative to the cost of living in the US today.
Well... "more or less" has a pretty large variance. My mother rents a 2 bedroom duplex in Idaho for like $500/month. In the Bay Area I could probably rent a tent in my backyard for $500/month. A person making $150k/yr where she lives in Idaho is going to be far better off than a person making $250k/yr in the Bay Area.
