The point of my reply was that saying that the US has more money does not explain the fact on why people in the US pays more for software than in the rest of the world, which I believe is the key issue when it comes to a social network ability to monetize international markets. You have rampant software piracy in Latin America, Asia and Europe. At least in the EU, things are better for business software. China is so notorious for piracy that a former head of Microsoft R&D for China said: "In China we [don't] have problems with market share. The issue is how do we translate that into revenue.".

Nowadays software companies in China have found success by giving away free games and selling coins and whatnot. So my whole comparison was that if China has a bigger economy (or smaller/similar if you feel offended by that fact), then how do you explain that even large companies like Microsoft are struggling in that market.
