I have no idea how you got that from my comment. How much you make, how much you save, how much you spend, and how much you give away are all independent, and neither is it a zero-sum pie (for example, sometimes investments go down in value, and sometimes the line between giving away and spending is blurry).

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.
