sigh..... it has nothing to do with developers not knowing enough about css. Bootstrap has become a contribution effort from web designers alike. allot of the pre-made classes are well known and there for make very easy use when punching out code and giving it classes on the fly.

It's no different than a php framework, this is a css framework in a way. I feel like you are looking down on others when really i see it as being more intelligent way of developing quickly. Why re-invent the wheel when someone has done it for you.
