Not sure about this one.
Sure, good education helps a lot, but not all education is good, and sometimes (and it's probably especially true for startups) you will learn much more by just going into a field.
The most famous example of a successful dropout is Bill Gates, and I believe we have a few dropout here at HN as well.

Education is so expensive because lots of people want to get a degree, and high demand means high prices.
High prices do not mean that something is really necessary or useful for you - think of diamonds.
