It's not about countries, it's about cultures.
Some cultures (e.g. Western European culture) favor more serious subjects versus others. Some others (e.g. Northern American) favor lighter subjects (unwind-type). Asian cultures apparently favor explosive feeling-related and augmentative headlines ("It's SUPER effective!"; "AMAZING performance!").
Nobody's to blame, really, except companies not doing their homeworks and trying to vomit their own culture-specific successes over other cultures and promptly failing.
The difference is in the quality/richness of education. French/Europe get bored with useless drival from social networks. On the other hand, Americans like to waste time posting trivia. Another factor is the 6/4 situation with monetizing minutes of connection. Six minutes of important stuff and 4 minutes of commercials. How many crime programs do you need to see on the web?
We are shaped by what we visit. KISS applies more for North American users.
