Half the 18 year olds should be nowhere near a college - they enroll in programs acquiring knowledge that will only be useful shooting their mouths off on Internet forums, most don't even get an undergraduate degree, meanwhile they are now 20 and already in debt with college loans. Donald Trump promises that when he becomes President he will somehow force Apple to manufacture the iPhone and its other products in the USA - industry experts say even if Apple wanted to manufacture in the US they couldn't, a major reason why is the US doesn't have the number of skilled people qualified to do the job - our people are either overqualified/too expensive or underqualified to do the work required. Kids should be in tech/trade schools/community colleges after high school to get the skills to do those kind of jobs.
As for the kids who really are mature enough and have the motivation to go to school and get a degree, here's a list of hundreds of damn good universities in the US with tuition fees between $5-10K a year
2015 US State Colleges and University Tuition Costs Comparison Table - what's the fucking problem with that? There is no reason in the 4 months of summer vacation a kid can't make $5,000 - if the kid wants to live on campus or his own apartment, get a part-time job or Mom and Dad can help out or get a loan. Don't be looking at strangers for handouts, try doing it yourself with some help from those who brought you into this world. If I had my way I'd sterilize everybody over 12, white black and every other color in between, until they are self supporting human beings capable of supporting a child.
Anyway there's not a chance in hell Bernie Sanders will become President of the United States but 20 years from now most of his plan will have come to pass - the US was never the capitalist utopia conservatives like to harken back to, look at the income tax rates in the 1950's - the top marginal tax rate was as high as 90%. There were a ton of loopholes but even so the top tax rate was 50-60%. The US has been on a steady path of increasing socialism since the Great Depression, like the rest of the world's democracies. Reagan and Clinton let the bankers and the very rich get richer and richer without paying their fair share but socialism continued, the national debt is testament to that. As long as the US dollar remains the world's reserve currency I say just keep borrowing and printing money - who's coming to collect on it?
The US needs a flat tax with every loophole the richest and largest corporations and individuals use to avoid paying their fair share wiped out. Trump has railed many times against corporate tax inversions, he's railed against the medical insurance companies, would be very interesting to see if he came through on promises to do something about those.
Bernie would be a complete mess because he'd deliver on the higher taxes for everybody but he'd never be able to pull off most of his plan to pay for his promises while hurting small businesses, costing more jobs, putting more people on the public dole.
Trump isn't the ogre and moron he's playing in this campaign, if he were to get into the White House, he'd reveal himself to be what he really is - a New Yorker, more liberal than conservative, he'd appease the right who got him elected by being tough on immigration, supporting the 2nd Amendment to the hilt, and just good old fashioned American patriotism/jingoism.
