Not to mention, much of the prosperity of the '50's was a "fringe benefit" of most of the rest of the industrialized world blowing itself up for the second time in 30 years.
And of course there's survivorship bias: No one remembers all the terrible inventions of the '50's. (Had they come up with Smell-O-Vision yet?) All we remember is the transistor radio and the hydrogen bomb. Look back on the 2010's in 60 years and you'll see all sorts of amazing stuff that made its mark on the future, I'm sure.
