You can't say that for a fact, and you are probably wrong on that generalization. That same thing that drives people to be good in programming happens with it without schooling. And most of it happens to be experience. You can either pay for experience, or you can get paid to get experience. At the end of the day bad programmers from whatever walks of life are going to use list where maps should be used, and not understand algorithmic complexitie of the code they write. Processes, threads, and memory allocations are all system level operations and a programmers depth of knowledge of them are highly dependent on where in the stack they are working. In fact. I would wager that most self tough programmers are a cut above the average college grad, and way more suited to actually gettng work done. Thry have already shown they are self motivated and don't require hand holding to get the job done. Besides they will also be less stressed from not having all that debt.
