Why would going into debt to get a degree magically create a job? This is a classic display of macro vs micro economics. On a micro scale an individual always gets ahead of the competition by becoming over credentialed (and over educated helps too). But on a macro scale, all the local waitresses and bartenders already have fluffy non-STEM bachelors degrees so more education would merely make the average waitress a little older and deeper in debt, or make the high school grad janitor unemployed in favor of the new poli sci grad janitor. Its not going to deliver my food any quicker or make the bathrooms at the bar any cleaner, no economic gain at all other than bank interest (socialize losses and privatize gains!)
