I expect cultural mixing, and in any cultural mixing generally the culturally weaker a place, the more it will adopt outside influences. Often transmission of culture is a good thing: the spread of ideas helps creativity, and in theory positive advances should replace the inferior. But there's also a certain element where there's only so much head space to hold culture, and something has to go to fill it up with new things: stories, legends, traditions, customs, dialects and whole languages. Some of those that make way have a beauty of their own.
Secondly (and with relation to Starbucks) some of these are not in my view positives. They're just brute force advertising pushing identikit tedium, and difference is also nice. Don't we often travel to "broaden the mind" - experience something new? Surely there's a lot less fun going to other countries and finding they're just like your own: speak the same language, eat the same food, have the same architectural and artistic styles, etc. If you like anime, to a large extent you like it because it is the product of difference - another culture. The more alike that Japan and the USA are, the more anime would be just like a US cartoon. Would that not be a form of us losing something?
