Becoming an academic in CS for the sake of showing off would be an extremely dumb move. You get paid less than your students after just a few years, and nobody knows about you except some small clique of international researchers.
I do know of one or two in my area who seem this way, and I think they're very shallow people. And I know of some profs who are just kind of slackers. Maybe they though academia was something different than what it turned out to be.
But most profs are smart enough to know what kind of life it is going in. (A modicum of intelligence and societal savvy are required to get the job.)
