I'm not convinced that the higher-earnings thing with a B.A. is always true

Well, naturally, it's not *always* true. But I could cite many studies for you that show a very strong connection between holding a college degree and higher lifetime earnings, as a general rule.

I don't know the numbers on this, but I would guess that the number of jobs for plumbers, electricians, and skilled trades are absolutely dwarfed by the number of lost manufacturing jobs. Also, IMO, being a plumber, electrician, or mechanic requires above-average intelligence in at least some areas. I would hardly say these are obvious choices for someone with an IQ of 90. I'm pretty smart, but I suck at car repair.
