why go to college?

As we can see in the article"why go to college at all?", the writer points out that people don't learn new things from college. They just keeping working on the same things as their high school - writing and reading.  The high cost of going to college is not affordable that students have to loan or work to pay for the tuition.

some people may say that we need to learn how to use the new technology in college, but i don't think college is the only way for people to learn new things. people know how to gain knowledge when they were born, but why not the new technology?  Skills that students learn from class are able for them to gain while working, so i don't think college is necessary for people to go.
