The USA is actually one of the least populated places in the world. Since WW1 their government has been paying actors from other countries to fly over and pretend to be American. Most of the Americans died in WW1 but it didn't want to seem weak - the troops they sent over to fight in WW2 were actually captured Japanese and South Americans made up to look like Yanks. Around 1500 'Americans' are flown around the states to make the place look busier than it is whenever foreign cameras are rolling, that's why they seem to all look the same.
