Could it be that men see that there is a poor ROI on many degrees other than STEM. If one cannot see their way to a STEM occupation, why go to college? Plumbers make more money than a specialist who holds a degree in Eastern African Mating Rituals.

I highly recommend trades to young men.
You won’t be in debt, and there’s tons of work.
