People who enjoy programming and long stretches of mental exercise are rare, and have been rare throughout history.
I didn't get into tech by a boot camp or something I was originally in phys/eng but picked up building LAMP websites on the side. Took me like 3-5 years before I actually made money from writing code.
An aside, but I am truly concerned that our path from working to professional class via tech work is closing up behind us.
I think the key is the understanding that programmers are are properly paid for their work, and now we need to make sure teachers, janitors and garbage men and the like get to have good, stable lives. And yes, I think janitors and garbage men should make as much as programmers.
Yeah I'm not sure about that, although I heard like in NYC some garbage men make close to $100K.
I still believe in proportional compensation based on effort eg. a doctor otherwise why try.
