The "he lived in Daly City" thing is a bit of a red herring. Daly City was not a 15 minute drive from the center of the hottest industry in the world in 1963. So substitute Fresno.
Anyway, if you can find a woman who wants to be a SAHM to your five children in a Fresno starter home, where she clips coupons and cooks meals from scratch with no appliances, you can achieve a 1963 standard of living pretty easily on a schoolteacher's salary.
