Oh, certainly it is. There are a lot of union jobs that pay well, though admittedly the better-paying ones require quite a bit of skill. My brother is a pipefitter, and while he makes more than many software developers, he is also qualified to handle pipe work (layout, welding, testing, etc.) in hospitals, hazardous chemicals and treatment plants, etc.
My father also runs one of the few remaining foundries and employs some semi-skilled, decently paid labor.
But, nether of those industries current employ enough people to make up for all of the folks who would want them. Or at least, until our infrastructure bill comes due -- a significant portion of the 50s and 60s era suburb/exurb buildout will soon require substantial investments just to have water/power/roads continue to function.
