I had a friend that was seriously looking into this. He ultimately decided that it would be more fulfilling personally, and more lucrative financially, to get his GI Bill to pay for trade school. He spent 6 months in school and became a welder with a boatload of certifications in a bunch of processes and positions, and takes a couple weeks to a month off every couple months and goes and dives with no responsibility, nor personal financial burden.
I think his (paraphrased) words were, "the number of instructors without a second job that don't make poverty level wages could fit in a room the same size as you'd need to fit all the honest politicians in Washington."
