This thread is about the equitization of higher education with future income. Why is this post irrelevant and posted here? Stay on topic, please.
One thing this scheme encourages is for newly grads to take on less lucrative jobs (not that newly grads would be paid with hefty salary on their first job anyway) if it means higher payer would result in higher % of pay being forked over to pay off the debt. The newly grad would much prefer to take on jobs with lower pay or better yet with just a stipend for living costs but would give them more experience and that would leave the investors holding the bag or at least for longer time. Also does this "education stock" come with options? What if the grad never gets a job or gets a job that they are "overqualified" for or underpaid? Does it come with put options? Without options to mitigate losses, it's a might risky investment. And honestly humans is one of the riskiest investments when you can have Harvard Ph.D. grads flipping burgers.
