First, for anyone reading this, this post refers to this:
http://www.coalpha.org/Post-Game-Culture-tp6256108.htmlI am not sure how you define "feminist" but I would define it as a slut-power movement. So let's look at your list. Southern Italy up to Rome is the left-over of the Roman Empire. Northern Italy had the benefit of numerous invasions which introduced other cultures. Rome itself was feminist during its decline, so most of Italy, except the north, is post-feminist. (See "Sex and Culture" for details about feminism in Rome.) In Argentina, they had Eva PerĂ³n as president who promoted feminism in the early 1900s. I don't know about Mexico since it declined before Europeans arrived.
I don't think wealth and technology will make any difference. Rome lasted quite a long time in spite of suffering from game/feminism. I think what matters is how much power a society achieved before starting to decline, and how powerful its adversaries are. Rome benefited from starting with a lot of power and no serious adversaries. The West is in the same position today.
