Do all uneducated people act like assh*le?
What nonsense. Education is completely unrelated to character. There are just as many educated (people with a degree) assholes as there are anywhere else. My experience is that many people with higher education tend to have an over inflated sense of their own self-worth despite poor character. Higher education is no stepping stone to good character. Also, people who work in the service industry make society work and their character is not dependent upon a piece of paper that confers academic compliance.
You tend to generalise.
