Just as with Nostradamus, bible, etc. "predictions" they kinda sorta came true if you squint at them the right way. And there are enough true believers to parrot praise in unison. However, a more objective look reveals that these "predictions" are way off.
A guaranteed income,
Welfare, housing assistance, charity. It's rough, but the basics are provided for if you go out and get them.
That is NOT guaranteed income. Welfare (in US at least) has existed since 1935, so that's hardly a prediction.
Underemployment. College grads are flipping burgers.
Not to the level that was predicted, and certainly not to the level afforded by guaranteed income.
and strict population controls
China did it. But yeah, it's really not a problem for first-worlders. Asimov didn't see that coming.
Precisely. *One* country has a problem with overpopulation. And their solution is NOT strict population controls, but economic disincentives for families that have more than one child (so it costs more, but rich families can afford it).
would all have much, much larger effects on the world we live in
You're using the term "would have" like these things didn't come to pass.
Because it fucking didn't. Quit trying to see things that are not there.
