The United States is a prime example of a society with a huge rich-poor gap. Some economists say the solution to disparity is not to redistribute wealth, but to expand. If more people have greater access to global markets, then economies grow and there is more wealth for all to share. These are just a couple of the reasons we have become globalized. And, we just like the idea of expansion.
Globalization is synonymous with freedom and economic growth.
Controlled growth is good. It's hard to convince free enterprise that some restrictions are good though. This is the challenge of the environmental movement today. There are several reasons to be fearful of liberalized trade. One, expansion does not recognize the costs of resource use and depletion.
