The laws were also different though. Trickle down economics is a fairly “new” concept (and total failure) and that has certainly fucked the economy up. By cutting taxes to the wealthy (among the many other laws that benefits corporations over individuals, etc) the gap/disparity between the haves and have nots has increased tremendously. A vacuum salesman in the 70s/80s could afford a house, children, etc. I don’t think they were lucky but they also didn’t have the chips stacked against them.
