I think it would be more accurate to say that developers don't really
have time to figure out how the database really works, and dba's don't
really have time to figure out how the developers are programming.
My thoughts on the agile programming technique that someone mentioned
here is it adds more in confusion than its worth in speed.

That hasn't changed much in 14 years.
Much of this ignorance of how an efficient (as in scalable)
database should work is due to the Microsoft 'black box' programming
methods. Developers don't know many of the building blocks they use
really work, and are not encourage to find out how things work.
You don't need to know all the internals, but you do need some
idea of how things work to use them efficiently.
Just to be clear on this, I think it would be great if all developers
had an interest in how the database work, and the hows and whys of
database design.
The problem just seems to be that they are often taught that it is not
necessary.
