Some people want to break out of the cycle, and you can't really blame them for it when the economy is hurting working people (ofcourse excluding that writing software is relative to other jobs a cushion job)
Software is the most cush job I have had. More money for less work. Better perks. Less stress overall. Constantly learning, yes. Often frustrating, yes. But having financial resources beyond what the other jobs could provide is a thing. Other jobs I could leave at work, sure, but others I couldn't. I would never go back to being a public high school teacher; that shit was the suck. So was selling stocks. Software is a dream in comparison.
The problem is: there exists a very specific group of people who do software development as a job who are really passionate and idealistic about software (that's why they actually got interested in software development and decided to do this professionally). For these people, the whole "politics" about software devlopment, bullshit project management processes, not being allowed to make use of their full potential and skills, and office politics is (thus) hell on earth.
I thus very plausibly do believe that exactly for people who are incredibly passionate about software development, other jobs (that are outside their passion) can actually (paradoxically!) be more convenient.
