Higher education in the united states is an optional final stage of formal learning. Many people do not participate and many are better off for it.
I am surprised at the number of kids that do not want to continue education.
Some call it tertiary education or post-secondary, I personally am a college student persuing a PharmD 
That is great and I am sure a lot of hard work.
