And would we imagine a society of capable, educated, useful people is not preferable to a society of ignorant unskilled people? Why would we wish that on ourselves? How does that improve the world?
Even worse, the implied understanding that our society cannot function without an uneducated subject class is worrisome. Are the socialists right, and Capitalism/the free market demands a slave class?
Anyway, with automation any such demand diminishes yearly and is already small.
