Yes, yes, and yes. Janitorial staff at a Ford plant in ~1965 would make enough to own their own house, vacation once a year (probably not by plane but...), and college was percentage-wise ridiculously cheaper - 30x if my calculations are correct, which they probably aren't, but hey. Healthcare would have unquestionably been provided by their employer. And all that on only a single income for a family of four, no less.

... and with a defined-benefit pension as well, meaning no need for 401k contributions out of their salary, and no risk of losing that money due to poor investment decisions.
