There’s a mythology that boomers could just graduate from high school and buy a house and two cars on one income at a factory. Then they could work for that same factory until retiring with a pension. Mom could stay home with the kids who could then all go to college with no debt.
I’m surprised these are that high. The typical thing people think going back is that boomers and Gen X got married at 24 and 27 and then bought houses. Clearly not.
