There's also a lot of charts like these out there that all tend to show the same thing.

They use GDP per capita as opposed to just GDP as it's more an indication of just how well off "everyone" is as opposed to just saying what the economy is doing.. i.e. if the US had a billion people living in the country with the same economy, everyone would be a hell of a lot worse off than they are now.
