You could substitute the word gentrify for globalization. I think the commentor just means that there's a cost when enough immigrants come to a place. I wouldn't call it ruined like they did but it definitely does cause change and some things are lost to the mixture.

I think the word gentrify makes a lot more sense, good point.

I think mixing human cultures can be very complex (human social culture is certainly some form of a complex system) and you're correct that it can cause a lot of change and possibly danger like culture getting erased. When cultural integration is done well, it can cause a lot of beautiful things to happen: appreciation and love of the culture(s), sharing the culture, and fusions of culture. Please note: The above is a lot harder said than done.
