If you assume that everybody was pining for the good old days of segregation, then yes, going back to the 1950s sounds intolerable. If you think about it more as nostalgia for the entertainment elements of American culture --the movies, the TV, the music, etc.--then it's not so scary. Also the economy was pretty damn good back then; it is not at all unusual to hear somebody like Michael Moore (no Trump supporter) saying (with dismay) that this isn't the same country he grew up in. Back then you could graduate high school, get a good job and start a family. Pretty soon you were buying a new car every two years. Wouldn't you like to see income inequality at 1950s levels?
