Jobs like working in mcdonalds obviously require a certain skillset, but that skillset can be taught in a very limited timeframe, as opposed to skilled jobs where that educations takes a much longer amount of time. I'm saying that the availability of such jobs seems to be on the wane.

I appreciate that such jobs are undesirable, but they're much in demands by those unable to take up a skilled trade, or those whose skillset has been rendered obsolete. They might not be great jobs, but they beat the alternative of nothing.
