How and why is this organization, the Center for the Study of Globalization, allowed to exist in the US?

Note that their first agenda item is Global governance, next is Global economic governance.

The purpose of this organization is to make the US Constitution and Citizens subordinate to a world government!! That is subversion against the Constitution!! And it is supported by many politicians all the way up to President Bush.

Now the kicker. Look at who the Director of this organization is. Former Mexican President Ernesto Zedillo!!!

Obviously this is supported by multinational corporations that want global economic control. I call it Corporate Facism.
