As we've gone through at nearly every discussion about voltage; not all American homes/apartments have a "panel" with 220v power coming in, and upgrading (when possible) can be an expensive undertaking. Miele found this out for years trying to push their 220v washing machines with only limited success. A good portion of the time deal killer was the voltage. That and the perceived small capacity.
Here in NYC we have some of the oldest housing stock in the country. You have multi-family housing from our very best homes on Fifth Avenue to Lower East Side tenements that went up in the early part of last century, if not before. In many instances their electric capacity is what was installed to suit, and has not grown.
Know plenty of persons living in apartments with around 80amp (2 twenty amp fuses, and two 15 amp) total amperage. Only reason fuse box was up graded to two twenty amps is one is for fridge (in kitchen), the other for AC (outlet near window).
In many instances it isn't even just a matter of running more power from the main box in basement/meter. But rather increased supply must come in from the mains outside. That involves ConEdison, a licensed electrician, breaking up sidewalk, installing new panel in apartment, running the line up from basement......
Fast forward to today much new construction and major renovations are getting 220v lines because people are demanding washing machines and dryers. It is not always possible (or wanted) to run a gas line, so people go with electricity. Besides many of the "compact" European dryers do not come in gas anyway (Miele no longer sells gas dryers in USA), so again you are going to need 220v power.
The other reason is one we've discussed before; post WWII much of Europe was rebuilding housing and infrastructure that was damaged. Decisions were made to go with 208v-240v at 50hz (yes, I know) power as the standard. As mod cons had not expanded greatly (and even if they had large numbers likely would have been damaged or destroyed during the war), it was easy to mandate that switch.
Across the pond USA saw no damage to infrastructure and basically simply carried on. As the expansion of electricity continued to rural areas that didn't have they got the same service as elsewhere.
Also as we've discussed one of the prime reasons for all that "high power" in European homes was for washing machines and dishwashers to heat their own water. American homes largely relied upon central hot water from a tank. Energy for heating could be provided by any of the "cheap" but (then) plentiful natural resources (coal, natural gas, oil), and or if you lived in certain areas where electricity was basically being given away.
Long story short the die was cast and don't see it changing in any large way. People and or businesses that need 208v-240v power can usually get it if they wish.
