>For safety, look at the standard US power outlet and compare its safety with practically any other outlet in the world, of which all of them are considerably safer

You judging the U.S for something they did first is only proving the point. It'd be great if we could up our voltage from 120 and change the plugs, but after a point it's just too expensive to change. And it's not as if tens of thousands are dying due to 3 prong outlets...
