This is pure speculation, but I think the devaluation on PhDs in America might have to do a lot with the large of influx of people in college just attending to &quot;get a degree&quot;. I feel this made colleges more of a business than a place of learning with the large increase in revenues, and thus leading to PhDs and fields that aren&#x27;t as respected or really don&#x27;t have a basis for being around other than people are willing to pay for it.
