It's quite an interesting topic. Unfortunately the article meanders slowly through some interesting examples in a long-winded style.
The conclusion of the article and the title is a bit puzzling as it briefly mentions only one dutch study that concluded that people in the north and the west (richer countries) tend to cry more. Even though the research was about _reporting_ to cry more.
Emotional people might not feel like reporting that they cry maybe?
1. Self report of crying might be reduced by those in more hostile environments as they are conditioned not to show weakness.
2. The behaviour of crying is learned as a way to get support from others(this is not fact, just speculating). If that support never comes, crying would not be reinforced.

It's just not explored.
