From what I've seen, I don't think they actually expect to meet George Clooney. After living with their independence and high paying job, 100% of which they can spend on them-self, usually enabling tons of international travel. They don't actually want to settle down and put work into a relationship, but their friends and family constantly pester them to do so.
So they settle for appearing desperate to keep their friends and family happy, but keeping standards high so that either the sacrifices to have a relationship would be worth it to them or they don't get a relationship they didn't want anyway.
