It was an example
There is plenty of people out there in professional world with no college degree.
And at 3 you start the murder?
hehe
Seriously?
The reality is this, your example sucks. There are three guys (and perhaps a handful more) that fit that profile:
1) Steve Jobs
2) Bill Gates
3) Mark Zuckerberg
These people are not the norm. No can say that college makes one better than another. The simple fact is, in some positions, you benefit by having a degree. It makes you more qualified than someone else.
I work in an office, and we have a handful of everyone. College/no college. Smart/dumb. Etc. Perfect example is the SQL admin that we have. She is quite intelligent in what she does. She learned everything she did along the way. She has been promoted to manager of her department, and oversees a college educated SQL admin at this time, while still managing SQL herself. She has no college education.
However, if she were to apply for a position at a competing company, her work experience is negated by the absence of a degree. Her subordinate would actually rank higher than her on a majority of company's searches, despite not being as technically inclined as she is.
So, while the degree doesn't make you smarter, it usually makes you more qualified. Your skills and earning potential won't be limited to the organization that you built them in.
The three gentlemen I mentioned were much smarter than 99% of those around them. Their intelligence allowed some pretty amazing things, and some pretty incredible earning potential. Odds are, most will have a better chance of success in their career path with some form of higher education. For every guy with "just" work experience, there are another 5 people with degrees doing less and getting paid more.
I recall another conversation with an IT pro who was turned down for a promotion due to a lack of a degree. They later decided he was the best one for the position, and called him back to offer it to him. He turned them down because he had already started the process of getting that degree.
