I'm not sure how that would work , the majority of the economy and employment is driven by business (there is also public sector and charity of course). Students need to get something from their college experience that makes them more valuable to someone who can pay them money otherwise it would be difficult to justify the fees and debt, especially to those from lower to middle income backgrounds.

I'm not convinced that academics are better qualified to predict the needs of society regards knowledge and education any more than the free market is.

Regards to helping students evaluate themselves , there is no reason that a professor cannot provide feedback in addition to assigning grades indeed I'm sure many would be happy to and it's more likely a case that many students are simply happy to get their grade and move on rather than evaluate themselves.
