The 'Mad Men' actor can't understand why Hollywood has rejected the idea of an ''elite'' of talented stars in favour of personalities acting like ''f***ing idiots''.
He said: ''We're at a place where the idea of being elite is somehow considered a negative. Whether it's Paris Hilton or kim Kardashian or whoever, stupidity is certainly celebrated.
''Being a f***ing idiot is a valuable commodity in this culture, because you're rewarded significantly.
''And incuriousness has become cool. It's celebrated. It doesn't make sense to me.''
Jon struggled to get his big break in Hollywood and gave himself a five-year deadline to land a major role after witnessing how ''depressing'' it was seeing other actors flounder for even longer.
He added: ''I knew a few people who had gone a little longer than that and it turned into a depressing model.''
The 'Bridesmaids' star also admitted he isn't impressed by aging Hollywood stars trying to cling on to their youth.
He told Britain's Elle magazine: ''A town like this not only celebrates but insists on The Cult of Eternal youth, so I can see how it happens. But if you're in your forties and fifties and you're spending two or three hours in a hair salon getting your highlights done... Well, that's not my game.''
