I'm seeing a lot of comments from a HR perspective or that once they get the training they leave. To me it's much deeper than that. This industry of software development only recently has exploded because it's much more mainstream and the demand is growing.
I feel if we compare it though to other trades the issue is simply the industry as a whole has top-ended and completely changed itself the last 7 years each time. I've seen Senior Devs take a junior role at their next company simply because the rate of change is so fast.
This is not a trade like plumbing or even electrical work where once a way of doing something is set in stone and you'll do things a certain way the rest of your career.
If you told me 10 years ago I'd be writing javascript all day everyday...
