I'd actually expand that to European - in my grad studies, the European CS world had a much more mathematical bent. Notice the the Glasgow Haskell Compiler, Coq, etc.

You can always go from math -> pragmatism, but the reverse is nearly impossible. People get set in their ways, and it takes time to develop mathematical rigor, even if you want to.

So when you need to get mathematical expertise, you wind up needing to hire it.
