It's silly to lump Europe, the UK, the US, Canada, and a bunch of other areas into a general concept like the West. They all have unique cultures, and they all do plenty to preserve them. The US is also not a single culture, it is an incredibly diverse nation. Every state has a unique culture, and within those states there are a ton of unique communities.
Boo, you were right to call me out on the carpet about my list. I was throwing out a few names with very little information, because I know very little about that part of the world. I've never spent time there, and all I have to go on is what I read in the news. I am fairly ignorant on the subject. But that is what kills me about the folks here who attack the US. They are also not well informed, and yet they repeat the same ignorant garbage time and time again.
I spend my summers visiting cultural landmarks all over the US, and I can tell you with certainty that the preservation is remarkable.
