im sure you cracked the code.
Well, yes.
Free college doesn't work when your university landscape relies largely on private universities.
A post-industrial economy also doesn't require more than 25-35% of its workforce to be college educated. The US is already at around 30% and the economy doesn't need more. I never heard Sanders propose a plan how he wants to restrict access to free colleges to keep this number at around 30%.
Even if private universities would kind of take a step back and a free public system would take over, you'd still need an alternative education route to educate the other 70% of the population who wont go to college. High school alone won't suffice. All those people will lose their jobs to machines and AI.
9 out of every 10 jobs lost since the year 2000 were lost due to automation.
Yet, in 2016 the US had a record number of job openings.
The issue is blatantly obvious: The education system is designed for the economic realities of the 1950s, but the world has moved on.
And now you have an education system that produces workers the economy doesn't need anymore, and the economy is struggling because of a lack of skilled workers.
Secondly:
Universal healthcare won't work unless you have public nonprofit insurance companies, operating nationwide. Health insurance also has to be mandatory.
Sanders proposals were incomplete.
