Why are electrics so complicated in the US

I've been reading a lot about your electrical wiring in the USA and from the UK, I'm baffled on how American electrics have become such a complicated mess. You seem to have 10s of different styles of outlets, split phase, 120v and 240v, a tranformer on nearly every utility pole, no ground wire sleeving, wire nuts, flimsy unsleaved plug pins, and can't even have an electric kettle in your kitchens , oh and your tumble driers need special outlets too. I quite feel sorry for you as I'm sure most Americans would rather a one size fits all approach with one type of plug and one voltage. I guess we are just lucky in the uk to have such a relatively simple electrical system. How do you feel about the mess your ancestors created in America with your electrical system?
