Isn't this true for the vast majority? Most people take jobs not because they're passionate about them, but because they need money to pay bills and buy stuff - simple as that. Some earn more, some earn less, but at the end of the day almost everyone would like to do something else. Even in IT, where wages are high and work is comfortable, I doubt most are passionate about their work - it's a different thing hacking some fun app or game in your spare time and working on some monstrous enterprise software, where you're just a tiny cog doing what you're told to do.
