The salary numbers are very optimistic, too. A small number of tech workers at a small number of FAANG companies in a small number of locations, will be making $250K from the start or even average that much throughout their careers. I know, I know, everyone on HN makes $400K and drives a Ferarri, but that's very optimistic number for most people.

EDIT: Also: house should not be included in your net worth for the purposes of calculating retirement draw-down, unless you plan to liquidate your home equity to live on.
