Here in Cyprus, although our culture is deeply connected to British since every second Cypriot was either born in UK or has British relatives, and it is a former Crown possession - dryers and dishwashers are standard equipment even in cheap rental apartments.
I can imagine in US it is harder because voltage is 110V vs our 240V, requiring thicker wires.
The US has a "split-phase" system - two opposite 120 phases off one transformer that get split 50/50 among the breakers in the house. To get 240V outlets, you go across both phases instead of from a phase to neutral, so they add together.
