Sorry, my phrasing was bad. Totally agree, even today trades are still AMAZING for this. I meant even if you were to set aside the trades, 50 years ago there was plenty of stuff you could at least support a family on without even that level of specialized skill. You could "start in the mailroom" or on the sales floor and end up in middle management after 20 years, in a variety of companies, most of which don't even exist anymore, or if they do, they employ far fewer workers domestically today due to a combo of offshoring and automation.
