In the last sixty years, a tremendous amount of money has been poured into education. Much money has been allocated to increase college enrollment. But, IMO, for the vast majority of people, college education is a luxury social club. Spending more money on college is just a wealth transfer from tax payers to upper middle class teachers and administrators. I do not agree with Peter Thiel when he says that kids should start businesses instead of going to college. But I think there is lots of room for designing some sort of adult-life on-boarding process that was far more cost efficient than having the government write a check to subsidize teenagers getting black out drunk every weekend. I'm not sure what this system would be, but there are lots of options - could be some sort of apprenticeship, or a co-op mixed with classes, or a light-weight, low cost online education combined with assigned mentors.
The real issue is that any form of labor that is a commodity, and that does not have union or legal protection, has been screwed over by the trifecta of globalization, immigration, and automation. But, I disagree with both the neoliberals and progressives in that I do not think it is possible to educate the great masses and enable them to find non-commodity career paths. There are only so many content marketers, enterprise salesmen, management consultants, and product managers that the world needs. Those jobs are going to go to the genetically and socially privileged. Therefore, the only solution for the normal person, who will be at a commodity job in customer service or doing sales at a Verizon store, is collective bargaining.
One form of collective bargaining can take is democratic politics. My policy preference would be a law that creating a universal wage subsidy of $7.75 an hour, thus guarantees every worker a total wage of at least $15 an hour. I would couple that with a "job of last resort" program that would replace long term unemployment and disability insurance - everyone who wants to work can get a job, no matter how blighted their city, no matter what kind of disability they have. Even if they are a quadriplegic they can be assigned to monitor security cameras or something else.
