Union elections in the bay area rake in about 140k/year after 5 years on the job. Highly competitive, but no college required.
If I could be reasonably expected to make that in my area (Philly region), then that sounds great and is substantially more than I make as a dev.
Im not saying it is the best job in the region, just demonstrate that blue collar jobs can still provide a comfortable living with such salaries.
I would expect it to scale by regional COL.
