EDIT:
Talking about "lower class", I didn't mean it in an elitists way, I'm sorry if it sounded like that. Probably I should use other words than "class". I wanted to explain that many technical people in IT business (programmers, engineers...) kind of put themselves down with their soft skills, manners or the way they behave. Like they are really clever and skilled but the way they behave make them look somehow "lower" many of them can't ask for the money they deserve etc...
