Construction is not always “simple” work (use that word around a master tiler, for example)— liked this article until this choice of wording, which fairly negated your whole attempt and presented a position of privilege that whitewashed the whole thing.
In fact, these days, training for a vocation is probably a much smarter thing to do for many people than wasting time and money on a liberal arts degree and student loans. I know people who work in garbage collection because it pays better and offers them job security, not because they are “simple” jobs.
