After the Soviet Union collapsed and the Cold War ended, we've already seen what the world will be like in a world where there is only one superpower, namely the United States.
Personally, I would fairly say that the United States has successfully used its clout on all possible areas that human beings can indulge into: politics, economy, science, the arts, etc. It has become so successful that it was able to exploit the world's developing nations, or help them succeed, depending on your point of view.
But time will come when it will step down in favor of new emerging powers that will lead the world someday. Back in 2001, Goldman Sachs named these countries as the BRIC nations. BRIC stands for the names of the four nations that, in Goldman Sach's opinion, have enough potential to be the world's largest economies by 2050. These are Brazil, Russia, India, and China.
Though Goldman Sachs does not argue that they will form an economic bloc in the future, it is already noticeable that these four nations are starting to make a political bloc of their own, advocating the rise of a multipolar world order in the future.
So where does Mexico enter in the picture? Basically, what the thesis says is that the country, along with South Korea, are the only two nations comparable to the BRIC. The reason that they are not just included is that it is widely considered that the two are more developed. In the case of South Korea, one can already say that it is already developed.
Mexico, on the other hand, is still considered to be an emerging market. Living here is relatively good, although growth is still exceptional. In a few years' time, expect the BRIC to overtake this.
So it is time to transfer to Brazil yet? Perhaps not. Who needs to be in a global power anyway if you just want to be an expat?
