For Globalization to work, you need a global Community

Which does not exist, and is unlikely to ever exist. You can put this another way, and speak of the need for a global civilization. 

This is also unlikely to exist, and for the same reason: we developed as tribal people, of about 100 people for each tribe (each with its own language). That way, everyone in the tribe knew everyone else. 

A tribe of millions of people is not possible.
