The US is 4% of the world. With other countries developing rich consuming middle classes, that might not be that certain, especially in the future.

4% by population of course, which is what you meant, but I think 40% of the world by wealth. While I understand what you mean by saying there are new middle classes being created from the other 96%, it seems like, absent another even more catastrophic economic screwup than we put ourselves through 8 years ago, American domination of the world market isn't going anywhere any time soon.

[eva1984]

In terms of GDP, US is about 20-25% of the globe. It is pretty significant, but I won't go too far to say it has domination.

[davidmr]

Well said. Domination isn't the right word; perhaps "importance to" rather than "domination of".

[coldtea]

Well, let's hope it does. Other people need to get rich too.
