> Then you quickly reach a point where you can eat a raclette anywhere, soccer is the most famous sports, Hollywood is the main entity broadcasting entertainment. There is no point in traveling, because every place more or less lost their spirit.
Less traveling would probably be good for the world, but it's not true that places "lose their spirit" just because they've got football, Hollywood movies and raclette everywhere. They already have that everywhere, and almost everywhere is still interesting and unique. Just more accessible, leading to more travel.
Cultural exchange is useful and valuable. What's a problem is when desperate people have no buy-in into the society. That leads to alienation, which can lead to all sorts of problems. But this can also happen to people whose parents, and possibly distant ancestors, already lived there.
