At the least, someone had to be about 18 years old in 1969 in order to have experienced the "50s and 60s" in some realistic form - that is, knowing how unions, manufacturing jobs that paid well and had good pensions, single-worker households, and so on were at that time. Those people were born at the latest in 1951 and are now at least 69 years old and largely out of the workforce. They are the ones who have been voting heavily over the last 20-30 years to create what we have now. And now they want the 50s and 60s again?
I think that's doubtful. I think what people want from the 50s and 60s is women staying at home instead of working, pre-Roe v Wade, fewer people of color - a white-first, man-first society with Billy Graham and no government telling you to wear seatbelts, a time when seeing the doctor was cheap and medicine was cheap. And whatever, as a white male even I don't agree with it. But trying to impose what existed in the 50s and 60s on today's world is stupid because the people who want it either 1) barely experienced it, 2) didn't experience it at all and have a romanticized ideal of it, or 3) don't really want the 50s and 60s, they just see this MAGA as a way to get a new white/male/Christian-first state.
