Why did I come to college?

I came to college to get a degree in business management.  Since I like the field of business I think it would suite me well to pursue a career in business.  I've did a little research and I've learned the average college graduate makes an average of about 40,000 a year.  I've been working since I was 16 and it's not hard to realize that with a degree I can almost quadruple my yearly income from past years in just one year. And in today's society the average worker will at least need some type of higher education, so naturally I would need some college education to live above and beyond the average expectation of a young male in this society.  I also came to college to gain knowledge not only for a job, but for myself.  Knowledge is key even without a degree I won't be illiterate or I can still no more than one way to accomplish my goals.  I don't necessarily think you need a degree to be successful but it helps a lot.  I personally know people who don't have a college education but have good jobs with companies such as the IRS and city workers.  So you don't necessarilly need a degree to obtain a good job, but it's more likely you will stay employed longer with some kind of degree.  My overall opinion is that it is very beneficial to me and society to get a college education.
