Hate to say the obvious, but it's all about supply and demand. The field I was working in 30 years ago was "hot" and the hourly wage has dropped at least 5x since then.

Sure, in the last 20 years I did "development" work which was related but more advanced (24 hours a day stuff, it's always in your head) - but once those efforts were complete, so were the jobs.

My field was laboratory science and I still take solace in the fact that 200 years ago, only the rich (or minimally subsidized) ever got a chance to to touch this stuff. But solace doesn't pay the bills.

Maybe take on volunteer work? Once you get involved, it leads to stories and sharing and new perspectives. I've done a few thousand hours over the past 15 years. It feels good. You chose to do it. You see results and have new ideas. Maybe even a new business.
