> Putting in long hours in your 20s and 30s to have a massive nest egg that will last you the rest of your life by your 40s seems like a good trade-off.

So, significantly less than what would be needed to hit $250K of pre-tax money ($6M or so), but rather a paid-off house (taxes and insurance only), no further college or retirement savings, tax-optimized withdrawals, and buying health insurance as the major effects. I’m guessing that it’s less than half of $6M (in today’s money) and probably under $2M to hit a 90th percentile spendable money figure.
