I can partly echo what you've said about Black comedians, although there has been a great progress if you compare Katt Williams or Chris Tucker with Kevin Hart, JB Smoove or Chris Rock. Maybe progress is also the wrong word, since Richard Pryor and Eddie Murphy were brilliant stand ups of their time. One quality of good comedians I might add is observational skills: To see the weird in everyday situations.
