The Case Against Education by Bryan Caplan

[LevelUP]

By getting a college degree you are basically virtue signaling to employers things such as diligence and patience.

The U.S. has a class system and if you don't have a degree, you are treated like a 2nd class citizen.  It is a lot easier in life to be walking downhill rather than uphill.  

Not that it's impossible to get a job without a degree though you will often see jobs say either have a degree or have 4 years experience.  So without experience, it's hard to start your career in a job that requires skills.
