IMO blue collar work is a better option because it's easier work and more stable, and lets you have a life outside work. In software the hours are increasing to no real benefit, and free time is burnt just keeping with the times. The evolution of tools, best practices and high availability of quality knowledge has made it trivial to spin up new hires which makes everyone highly expendable; not to mention that there are now millions of unwashed masses happy to accept lower wages just for their chance.
There was a HN post a while back where some guy was begging to pay for a code job. What does that tell you? Software workers are also now pitted against a global market with outsourcing and programs like H-1B which has raised the bar by increasing the pool of highly educated candidates and people who commit resume fraud. They're likely also more willing to work long hours for less pay just to be in the US. Software wages have also stagnated for ten years.
