The story might have been different if the 1st or 2nd child had a degree in computer science or business administration.
That only works if the student has interest and aptitude in those areas. The welder probably found a trade that fit both his interest and his aptitude. Had his oldest sister taken the same course as he did, she might be doing the same work she’s doing now. One hopes, for instance, that if she’s a writer she is using the relatively non-demanding nature of her salaried work to give herself the mental energy to pursue the discipline of writing. Just because one is not being paid doesn’t mean one is doing nothing with one’s education.
The main thing is that there are trades that need the people to work them, with only tuition keeping some would-be students from becoming valuable and productive members of society. What I don’t think we ought to be doing is putting people to work as university professors or trade instructors just to buy time for people who don’t know what they want to do with their lives. That isn’t a good use of our societal resources, regardless of whether the bankers are making their buck out of it or not.
For instance, there are some people who are wasting their time by spending it in a typical high school curriculum. I’m not saying the teachers aren’t doing their jobs, but that in some cases the task of educating certain of their students isn’t realistic because the students resist being engaged or aren’t cut out to connect to what is being taught. That sucks the soul out of everyone involved, not to mention wasting a lot of money and time. Ironically, this sometimes happens because high schools don’t have the funding to offer trade-oriented coursework or coursework students can use to earn college credits.
In the end, the students have to have skin in the game. If they have no money, then they ought to be working to earn their school. If that were the case, the students who are just buying time might just get a job while they’re trying to figure out what education suits them best. Some will still make choices that turn out to be wrong, but fewer will go to college just to put off growing up, which is a real drag on the quality of education.
