First of all, most conservatives who say “you should stop majoring in gender studies” don't realize that most people in debt didn't major in gender studies. Almost no one majors in gender studies, and blaming that for all of the problems with student debt and job prospects is just insane.
Second of all, no one knows what major is considered “good”. I have seen plenty of people go into majors like mechanical engineering or CS end up coming out jobless even though they send out hundreds of applications. So, do you believe the people who chose to major in mechanical engineering picked the wrong major?
The reality is that getting a good paying job has little to do with what major you pick. Stop blaming major choices for people being in a poor financial situation. It is not the problem.
