This is gonna be boring, but I might as well unload it. Not saying either method is right or wrong, better or worse. First, switched receptacles are available in USA, but are not standard practice for all outlets. Actually USA receptacle and switch systems are modular and the cover plates come in all kinds of multiples and configurations. The modern ones in UK seem to be all fixed "ready made" configurations. So in USA you can add a switch to any receptacle with a two gang box to accomodate both items. Note also that USA receptacle modules normally have to outlets one above the other, so typically you would be switching both at the same time. BTW: The house supply in USA is two phase, allowing for both "220V' and "110V" circuits - the former being mainly used for large water heaters, spas. cooking ranges. In USA all appliances are required to have their own on/off switches (DK about the UK). Usually manual but can be automatic - e.g. "semi-automatic" such as a central vac, garage door opener or "fully automatic" such as a thermally controlled roof/attic fan. Typically it is a whole lot easier and more convenient to reach for the appliance switch than go groping around the walls or under and behind furniture for the receptacle switch. But also note the standard location of US receptacles is about 15 inches above floor level which in not the case in other parts of the world.
Why Don't US Outlets Have Built-In On/Off Switches?
