It seems that everyone just gets a job for the money and not because its their purpose in life, does everyone have one?

Today it seems that every american is just trying to find a job that pays a lot of money and not out looking or doing what is their passion or "purpose". This surprises me that so many people are just working to make money and not actually out doing what makes them feel whole and have a sense of meaning or purpose in life. In my research I found that a lot of people who have good jobs, like owning business and leaders of certain companies of various types that still say they don't know if it is their purpose in life or meaning. A lot say they really don't know why they are here or what for on this planet. a common thread in my research says that they feel a longing for a certain something that defines and integrates their lives but don't know what it is. Something that it says help is reading book and turning to things to help them find what they are here for.There are a  lot of commonalities among people who end up finding their true purpose in life. One of the major ones is that they aren't very preoccupied with self-interest, in their ego-investments in what they do. A second theme of people who discover their life purpose is that they use mental and creative energies to serve something larger than themselves. 
there is no clear cut example or reason for finding a purpose in life and not everyone will or has found it but its what you believe and love doing.
