“Exactly where are the lower skilled folks supposed to earn money for food and shelter?”
I don’t have an answer for this, but I don’t feel too badly because the best economists don’t have one either. It may be that in the medium-term (dystopian) future, there really will be a “minimum payment” from the government. In reality, we actually have this now, disguised as the network of safety nets, (theoretically) paid for by taxes from the working.
The US is not the only country with this problem. One of the causes of the “Arab Spring” were educated youths with no prospects and no future. Europe has had this problem for years, but socialism tends to mask it with better “safety nets” than we have.
Obama’s solution is: More immigration.
So, are you saying you approve? That's ok with you? Because from your timeline, I'm not strongly getting the idea you disapprove with McGovern's 1972 Democrat Platorm:
"Probably the most liberal [platform] ever adopted by a major party in the United States". It advocated immediate withdrawal from Vietnam, amnesty for war resisters, the abolition of the draft, a guaranteed job for all Americans (it offered to "make the government the employer of last resort"), and a guaranteed family income well above the poverty line." - Wiki
Do you intend to vote for Trump in the US November general election?
