If I go to my doctor, or counsellor, or engineer, or mechanic, or... the list goes on... I care that they actually got an education rather than cheated their way through it. These are all things I can't personally judge competence in, because I'm not competent in medicine, psychology, engineering, etc. The most reasonable way for me to judge competence is whether an accredited school vouches for them via a degree.
