The difference is that Americans don't drink very many boiled-water drinks and so don't really need them. And the ones they do are easily handled and better handled by the specialized <100$ gadget that is a coffee machine.
Elsewhere in the thread voltage difference are brought up—that's probably what does it, typical US wall service is far lower-voltage than in Europe. That, and I've definitely had electric ranges in the US that were incredibly slow to boil water, so that might be a factor. Gas, though? At least as fast, depending on the quantity. (I hear induction electric is even faster, but have only used those a very little bit at a couple AirBnBs, so don't really know, first-hand)
