I mean the other 2 countries, Canada and Mexico, how similar are both of them to United States?? Both countries have a similar economy and democracy etc, and I think those two countries share things like supermarkets, stores, etc. I suppose the cultural differences are not a lot, that is very nice.
Everyone knows the only definition of culture is what year your city was founded and therefore how many old buildings it has. Oh and If you need to leave city center to see the ruins of the structures Europeans destroyed during colonization it doesn’t count. Only old buildings you can see from a tour bus counts as culture, duh.
