Pundits consistently underestimate how much income Americans make and how high living standards are compared to the rest of the world. Americans earn a lot of money, hence can afford bigger things in general, likes big homes or cars.
Americans are also notorious for spending their money and not having experienced the destruction of private property during WW2 and communism are sitting on a larger pile of inherited wealth.
The median income is just 20-30% higher compared to Europe.
