The high cost of higher education in the US is a significant financial burden on middle class parents and students. Therefore the investment needs to be carefully considered. Just like any business decision, smart investment means limited resources is allocated in areas that demand is stable or growing, and the supply side is not overcrowded by excess capacity. Students need help to get these information and college has a responsibility to provide.
Misallocation of resources, be it housing, steel mills or individual skills, will make the society less productive and everybody poorer. People in position to guide others should take on the responsibility to help our youth make wise decisions.
One more thing to add: we should encourage our youth to start using Coursera and EDX as early as possible. A lot of practical wisdom can be learned from there with very little cost.
