So you think it's good that 7 billion people, all speak one language, watch the same tv, share the same beliefs think the same way etc.
That's just fucking stupid. Culture is fucking important. All you gotta do is look at the White Death. It's a product of cultural transition, if you think the problem isn't anything but cultural your a fucking idiot.
culture is only as important as the people make it, and its only as valuable as it is virtuous. if everyone spoke the same language, shared the same beliefs, that would be a good thing? only if the language was good, and the beliefs were honorable.
globalization is about the world economy, not about culture. if tthe culture becomes globalized as well, so be it. thats up to the people to decide.
look up the term comparative advantage. free trade benefits everyone. the only down side is exploitatioon of foreign workers, which is something only globaliztion of politics can cure.
