As a result, a certain percentage of the population is going to follow their dreams and end up in a situation that makes them very happy, while another portion of the population is going to end up in dead-end jobs that make them unhappy. Those dead-end jobs need to be done even if few people will ever get much fulfillment out of them (I’m not saying that there isn’t somebody out there who could be happy in such a job, but that there are jobs that very few people could be happy doing). In essence, life is unfair because many people are predisposed by heredity or other factors to have natural talents in areas that aren’t lucrative and those people will wind up doing jobs that aren’t fulfilling.
