I'm looking for an answer to this question that is based in Marxist analysis.

You know what I'm talking about. Job positions that required advanced degrees when they previously required undergraduate degrees, positions that require bachelors degrees when they used to just require high school, positions that previously had no formal education requirements but now require a high school diploma, etc. Along with jobs that require more experience when they previously required less or even none.

The most common answer I find is more advanced technology but I don't think that's the full picture. Can you guys explain?
