"Most people in the UK have an electric kettle, but that's not true in the USA"

This has two causes: the prevalence of tea and the availability of 220V 10A kettles in the UK vs 115V 13A kettles in the States. Almost double the power means a boil in little more than half the time, making the electric kettle insanely useful.

New kitchens in the States generally have 20A outlets[1] so why won't anybody sell me a 115V 18A kettle? Make one for me, I will give you lots of money! The fact that it will have a funny plug is a feature to help you sell it by emphasizing its uniqueness and help you sell it, not an obstacle!
