There's another obvious theory that will explain that difference. It was easy to dodge the draft. You could say that those who didn't ended up earning less because failing to get out of going was a signal of incompetence.

Or, if you were aware that the problems they had in supplying raw manpower to Vietnam led the army to emphasize drafting people who should legally have been unable to serve based on their very low IQs, you could observe that it would be pretty shocking if veterans as a class showed equal earning power to society in general.
