Those are pretty strong statements from someone who knows absolutely nothing about me or what I do.  For the record, Arthur, I train students in a very high demand discipline who are highly recruited.  Many have gone on to very successful careers, and some are very highly compensated, well in excess of the $100k salary that you've determined is acceptable for me.  University faculty salaries are determined by a national market and can vary widely based on the demand for faculty in a discipline.  UA is part of that market, and if we don't compensate accordingly, faculty will leave.  I'm quite comfortable with how I've contributed to my students' futures, because I see the evidence all the time.  Nothing makes me happier than seeing them succeed, especially those who came from limited means.  It's one of the true joys of what I do.  

Who are you and what do you do to contribute you young peoples' futures?  Who are you to pass judgement on something you obviously know nothing about?
