Here's my pet unprovable theory. Development time is dominated by a programmer's understanding of a problem. Static languages force programmers to say a lot about their understanding of a problem. Dynamic code can be very fast, but in lisp, after algorithms, that means actually going and finding all of the calls to elt and replacing them by calls to nth. With a static language the compiler has a much better chance of specializing the code for you.
