But also you see people asking why can’t someone making the median wage - $75K a year - max out there 401K at $23500 and their HSA at $8300, etc
If the median income is $70k a year, after taxes they should be able to save $23500 a year and have an HSA compatible healthcare plan and max out their HSA?
To answer your question directly, $70k income is independent of the cost of living in high cost of living cities (like NYC or SF) vs. low cost of living areas. If you make $70k/year in NYC, no you don't have the spare income to max out 401k/HSA. If you make $70k/year working for Walmart in Bentonville, Arkansas, then yeah, I expect that you ought to be able to max them out.
