Something I don't understand (feminism/post game culture)
Basically, places like Southern Italy, Mexico, parts of South America etc are post-game societies. But these societies were unlikely to be feminist before they collapsed. Unlike many of today's game societies I don't see any evidence they were ever feminist societies. So are there two kinds of a game/omega society? A non-feminist game society (like Mexico) and a feminist game society (US)?
Also, another question about their length. Is the problem maybe with technology? That previous game societies collapsed really quickly due to them lacking wealth and technology to sustain it as long as today's society does?
I 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 Perón 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.
