I believe that the areas of study originally intended for the land grant colleges is, with rare exceptions, what schools should be teaching:
Engineering, animal science, agronomy, hard sciences, military science.
The hard fact is that the US economy needs exactly zero “english” or “history” majors. We need less than zero “womyn’s studies” or “critical literature” graduates.
We could add two years onto most high school programs and teach everything about business that anyone would need to know and turn them loose into industry, where industry would have to put some specific knowledge into their heads... and the kids would be able to start life without a crushing debt load.
How about just ending summer’s off and you’d gain 3 years of schooling.
