I highly doubt this is true of any country. All countries are full of humans.
Anyone making this claim has a severe sampling problem. If you personally don’t talk to people, you can be under the impression that nobody talks to people. The people that do talk to people can read signs for who wants to talk and they talk to each other.
The false impression is further reinforced if you go outside the country because as a foreigner people are more likely to talk to you, offer help, etc.
Your evidence would be stronger if you were a person who did care to talk to people but found that in a certain country nobody replied.
People are people, but people interact differently depending on the country. Here in France, what we often hear about the USA is that they have very different social norm. The usual story is: someone goes to the USA, they are successful, everyone is nice with them, they have tons of friends, then suddenly something bad happens to the person, and all of their friends disappear/refuse to help. So from that I deduce that people in France in general (at least in my sphere) have less but deeper friendships. That's not a judgment of value of course, but that's one way countries can differ.
Agreed, but to be fair people rarely mean it literally when saying something doesn't exist in their country - it was probably more in the vein of that 'it's uncommon'. There certainly are differences and in some cultures it's a lot more common that people talk to random strangers as compared to others.
