I am not sure I disagree but one thing I think is a little misleading is the comparison between the US havin 23% of world gdp and and 60% of world market capitalization. One small problem with that is that countries gdps are often compared by ppp (as in this case) and market capitalizations are compared in dollars. A more serious issue is that the US markets really represent much more than just the US economy. All the biggest corporations listed in the US have huge busnesses outside the US that count toward other countries GDP. I would guess WallMart is the most US based, but even they have stores in other countries. Apple is a US company that manufactures in China, buys important components in Asia and has employees and sells products all over the world.
