As far as expecting to make more because you went to college.... you may, but you will have a large debt in most cases that offsets the income.
Also depends on what career path you think you are taking. For some college is a must, for others, it's a nice to have, and the rest, a waste of money and time that could be spent elsewhere.
I suspect the heyday of college has come and gone and trade/tech schools are the new paths to success.
