If you can swing the training, even at the CNA or EMT level, there is healthcare. Purposeful work. Knowledge that helps your daily, and is never entirely useless. If nothing else it will save you from spurious trips to the urgent care or emergency room, or tell you when to use the urgent care instead of the emergency room, and save you money there. Even before ACA there were shortages. There’s potential here for fallout as with everything else, but if hospitals can retain nonprofit status I don’t see much changing in terms of need.
For now anyway, until nonprofit status/benefits get yanked, hospitals pay part of education upgrades. They typically offer better health insurance too, if you stay in their corporate system and don’t have kids.
I’m sure there’s other purposeful professions that don’t have an impossible buyin.
I usually recommend trades. Building something with your hands, again with a skill set that carries over into your household, has purpose. But with immigration policy, a sizeable piece of the grunt work force may be kicked out, so I’m not sure what will happen there but I suspect house building will slow down.
People almost always change over time. It’s why divorces happen over “where’s the girl/guy I married”? They don’t exist anymore, they’ve grown and adapted to life around them.
