I think McCain has in mind auto mechanics, computer programming and TV repair. Maybe this is his opportunity to increase the armed forces for his coming wars with AQ, Iran, Iraq, Syria and Islamo-fascism.
Auto repair is now a HIGH SKILL job that requires a lot of computer knowledge. maybe we can turn out a million or so of them so we can drive the wages down to minimum wage.
Computer programing along with computer production is now done in China and India .
