1) Have universities foot the bill, not the tax payer (shocking, I know). A literal refund.
2) Institute an audit every 5 years on their price to success rate on a per major basis. Have them refund north of 50% of the tuition if overpriced.
Cool, now run your little game.
This is literally a consumer protection issue and this industry has hid far too long under the veils of sanctity of “but tis’ but education, maaaaan”.

Like many have already mentioned, the federal loans going toward these costs are essentially like donating to a charity that you will never get actionable data on. Did the money go to the right place? Did it work? No? Okay, stop donating to that charity, as nice as it feels to be charitable.
If a charity doesn’t work, it doesn’t work, doesn’t matter how great it sounds. Even a charity named Education.
