Globalization only affects local culture when the local people allow it to do so. The Chinese can choose to eat at McDonalds, the Mexicans can choose to shop at Walmart, the Europeans can choose to drink Coke. And they do so en masse. Nobody forces the global culture on anybody. Ultimately, people vote with their pocketbooks. If people want American products, they will buy them. If they collectively decide not to buy them, the American corporations will not be profitable in that particular area, so they will leave.
