This is literally the platform of right-populism. "Wasn't it good in the 50s when a single income for a guy with an associates was enough to support a family in a life of comfort, and a summer job could pay for university? That's why women shouldn't be in the workforce and black people shouldn't have rights."
You forgot the part where they also give these people an easy target for the miseries in their lives.
"Do you hate your life? Do you wish you were living in a mansion, eating grapes lowered into your mouth by a servant, instead of working 50 hours a week? Well, have we got a deal for you! Just try Blaming A Minority, and all your problems will disappear! But wait, act now, and we'll throw in a second minority, free! Just pay shipping and handling, and vote for our fascist candidate"
Why is it harder for a black man to buy a house today, when he is theoretically richer because he doesn't have to give up his money to the man you described?
In that same time GDP produced per hour worked is up over 4x what it was then. There should be more to go around for everyone.
As for women in the workforce, having twice the income earners should double the household income. But two people can't buy what one person could back then.
