You're deliberately ignoring what I actually wrote. Two high school grads working minimum wage jobs in 1960 could have been homeowners in about five years. There are hundreds of reasons why the ownership rate was lower in the past.
You just handwaved away the graph, provided nothing other than the ridiculously vague, "There are hundreds of reasons why." And you are attacking them for having no argument?
I waved it away because it doesn't refute the facts. The fact is that a teenage couple making minimum wage in 1960 would be able to purchase a home in about five years. Nothing you've posted has disproved that. The fact that people chose not to do it is irrelevant. I don't have to cite the reasons why something didn't happen.
So, she actually had a job and could have kept it? A quick look at any source, including Superman comic books of the era, will show that there were millions of working women in America in the 1960s.
