That was my point, and why I wrote "simple" in quotation marks. Even jobs that are viewed as "unskilled" generally involve some kind of skill — farmhands, factory workers, customer service representatives, etc. Any job that truly requires no skill essentially has no job security anyway, as the worker literally brings nothing to the table. The actual complaint here is that the demand for various skills waxes and wanes.

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.
