I find this quite sinister. It's essentially saying that there is something psychologically wrong with you if you don't love the things you do to earn a living. In other words, don't you dare think that there might be something wrong with society just because you're working long hours at a job you hate. If your job sucks it's your fault. This attitude, if successfully inculcated, is of course very beneficial for people at the top of the food chain, who want passive and compliant employees. But it reflects an utterly barren conception of what life is and what might make it worth living.
