"Lumping all MBAs together is like lumping all programmers together" People do this with most things (they think all doctors carry around information about everything in their profession and every specialty). This is why I get a laugh when I hear from someone (people who chuckle about their computer stupidity) that someone, a friend, "knows so much about computers". I mean how do you know how much someone knows if you don't know about it yourself?
