The 1950s and ’60s are the middle and end of the Golden Age of science fiction
Incorrect. As everyone knows, the Golden Age of science fiction is 12.
Asimov’s stories were often centered around robots, space empires, or both,
OK, this actually calls for a correction on the facts. Asimov didn't combine his robot stories with his "Decline and Fall of the Roman Empire but in space" stories until the 1980s. And even by the '50s, his robot stories were very unsubtly about how thoughtless use of technology leads to social and moral decay. In The Caves of Steel, sparrows are exotic animals you have to go to the zoo to see. The Earth's petroleum supply is completely depleted, and the subway has to be greased with a bioengineered strain of yeast. There are ration books for going to the movies. Not only are robots taking human jobs, but a conspiracy is deliberately stoking fears about robots taking human jobs in order to foment unrest. In The Naked Sun, the colony world of Solaria is a eugenicist society where one of the murder suspects happily admits that they've used robots to reinvent the slave-owning culture of Sparta.
