Why do you think so? I've met some extremely entitled people with very few options in life, often because their entitlement gets in the way. In grad school I was friends with a homeless guy who insisted that he wouldn't take a job in which a younger person was his boss (he was in his fifties) as he felt he was a lot smarter/wiser than those people. So that ruled out a lot of job options for him. His backup plan was doing some work in construction and helping out a guy with a welding shop because those bosses were older and one of the few people he respected well enough to consider working for them.

Being entitled is a state of mind, in which you think you are better or more deserving than what life is giving you. It is a question of the heart, not the career.
