I wish he could have just said "we have an untapped well of jobs which sit between unskilled jobs and highly skilled tech jobs. Someone has to run all these new computers. If you go to a trade school, you can get a good job in less time and with no debt."
Heck, liberals and Democrats should be psyched for this message. Because: 1) people who graduate from trade schools join unions 2) green energy production needs these skills more than older oil companies do. Sun doesn't turn itself into electricity. 3) this sort of training is usually close to urban centers, which means more business for blue-leaning cities
