$300k a year is rich in 99% of the world and 90%+ of the U.S.
However, jobs that pay $300k vastly over-index to a few coastal major metros, where $300k a year is at the lower end of ever being able to own even a condo within a reasonable commute.
Yeah but then your spouse works too, and even if they only bring in like 80K that’s enough to cover living expenses, with the other salary covering housing.
