I'm no fan of college students who look their noses down on blue-collar workers but some blue-collar workers aren't innocent of doing the same to the white-collar workers and college students in my personal experience.
Granted, college has become more of a joke these days with what's being taught and the type of degrees they have and trades/blue-collar workers are needed in the world but it doesn't really help the blue-collar workers to shit on people who decided to study in college to become a doctor or engineer.
