I wouldn't even want to change for a successful young, white American male in the 1960s or whenever America was at its industrial peak.
Look, we are so lucky at this point in time in the Western world. Far from everything is great, but we live long lives in comfort, mostly painless, mostly without death or disease or hunger, mostly without war, we date around for fun during a decade or two, travel as we like, wherever we like, get entertainment on demand, chose our own profession, before we marry out of love when we are in our 30s or even 40s. Kings would envy our comfortable lives and I bet even Cary Grant would envy the dating life of a regular young man armed with Tinder.
