Even if you send your children to State University, they will be in danger and you will be responsible.
Agreed - if the parents approve. But parents cannot always stop or forbid their child from going away when the child gets to that age, but all parents can dissuade, and particularly for trads the dissuasion has to be built in, has to be a part of their upbringing - which hopefully goes without saying for trads.
If I have a son, I would encourage him to learn some trade related to computers so he can learn at home, maybe going to State University but only if he is mature enough
I think a great idea is to look into whatever the biggest industry or industries are in your area. For example, in Louisville, insurance of all kinds is one of their big industries, in Texas energy is one, in California it's IT, Detroit it's automotive, in Florida it's Tourism, and so on. I talked to a guy in TX a few years ago whose son was making over $115k/yr driving truck for one of the big oil companies from 9 to 5 every day, all he was doing was hauling metal pipes and pumps etc.. Most states that I know of have a choice of different industries to look into where one can make some really good income without any degree.
Within each of the bigger local industries, there are almost always great paying jobs that all one needs to do is learn via "on the job training." True one would usually start at the bottom, but within 4 or 5 years they should be making a nice income, after a few more years they'd be making even more, have a career they enjoy because they're good at it, and they did it without having to go in serious debt to get brainwashed at college.
