No, what we need are progressive taxes so that the people who get the most benefit out of society pay the most taxes. State taxes which pay for most public education including higher education, are regressive, falling heavily on the poor and the working class.
And people that get a college education are getting more out or society than those that do not, thus they should pay more. Even with progressive State taxes, the 20 year old high school grad who makes $40K per year in construction is paying taxes that partly pay for 20 year old his neighbor to get more out of society than himself via a college education and free room and board.
Also, plenty of college students already screw off and put no effort into it, barely graduating or dropping out. That's a lot of wasted money other people are paying for zero benefit to society. That would get much worse with completely free tuition.
So you agree with Loren that the only skin in the game that counts is money? That the students time and effort doesn't count?
The point is that many students don't put in the time and effort to begin with, so they have nothing really invested in it. For many kids, college is a way to avoid work and responsibility. The ones that invest the effort are those with internal motivation to actually get an education or at least look like they did, so they can make more money with their degree. For others, they lack this internal motivation, thus more immediate financial cost to themselves or their parents impacts whether they try to get more out of college than it being just a place to hide from adult decisions. For colleges with high entrance standards, they get more internally motivated students. For colleges that basically take anyone with a 1000 on their SAT, the student make-up and number of screw offs is not too different from average high schools.
You do understand that students that screw off in college get kicked out?
After many thousands of wasted dollars and after hindering the learning of most their classmates, the most extreme screw ups who fail most of their class for an entire year get kicked out. However, the more screw offs in a class (and free college will increase their numbers), the more they can get away with not really learning and stumble over the extremely low bar that is a bachelors degree. Course difficulty and requirements get adjusted toward the average student performance. The more screw offs, the lower the expectations and requirements to pass the course, meaning that they and everyone else learns less, meaning wasted educational resources. In addition, all students and profs know that their are many "fluff" courses that only require a pulse to pass. Padding their schedule with such course is a strategy screw offs use to avoid academic dismissal, while still not learning anything. And even a student putting in only the effort needed to get a C average and not get kicked out is still wasting finite resources and thereby harming others who would better use of that aid. Bottom line is that kicking students out after a year of a below 2.0 GPA doesn't come close to solving the problem of students that lack the motive to learn.
Here are a couple of uncommon suggestions that could address these issues:
1) Higher grades and graduation get students tuition refunds up to potentially "full refund" levels, which will incentivise effort and disincentivise students just wasting everyone's time and money spending years in school without real effort or direction.
2) Loan repayment is conditional on future income. Graduates pay back % of their loans, depending upon income during the years after graduation. This has a number of benefits. First, it allows education to serve its other important societal functions above and beyond just creating a skilled workforce. Second, graduates that get more financial benefit from their education will pay for more of that education.
Reread my discussion about progressive taxation. This is a much simpler solution, isn't it?
No, it isn't. My proposals are actually really simple and they actually address the problems while yours does not. First, yours does nothing to incentivize student effort which reduces the waste that inherently harms other people in need, because we don't live in fairytale with unlimited funds. Second, a college education is a benefit one is getting from society, so by your own "principle" (presuming you apply it non-hypocritically) means they should pay more than people making the same income without getting this extra benefit of a college education.
