There are many jobs that don't need a college degree and will pay well.
First, there is always mortuary science. People die regardless of the economic cycle, and is sounds grisly, but dealing with the bereaved and handling funerals does need people.
There will always be a need for plumbers, HVAC people and electricians. There becomes more of a need come construction booms, and people leave the field when the building stops. However, a master HVAC person will find work somewhere.
Welding is important. Yes, a robotic welder is extremely precise, but it will be a while before a robot is autonomous enough to go into the field to weld a metal plate onto the side of a building or do one-off metal fab work for a project (for example, I've had a local welder fab me steel cages so that some servers don't go missing that are used by a business in a crime-prone area .) Right now, no robot can do that on site, yet.
As for college degrees being stable... not in this economy. Even postdocs struggle in this environment, and people consider this economy "recovered" now. So, might as well learn a trade that pays as much if not more , and skip the six digit student loan debt.
: Ironically, this was a suggestion several years ago made on /. It has worked out well because before that, the local meth-using element would just snip any Kensington cables with bolt cutters.
: Good luck getting H-1Bs for plumbers and electricians. It will take people fresh off the boat just as much time to get their master HVAC certification as someone out of high school.
