I fail to see how this is a problem, and whether it should be fixed. The very idea that people that went through college deserve more is insulting for tradespeople as well as the source of bad incentives to go to college. If anything, the society would probably benefit from colleges focusing on transmitting and advancing knowledge, rather than being paid fast-lanes for people who only give a fuck about the payckeck.
This idea that some works deserve fair pay and some work deserve abuse (the worst being "burger flipper", "student job", etc.) really need to die. If you don't think it deserves fair pay and respect, you don't deserve the service.
