Law of averages bro.
If you have 9 places to live, (Really a lot more than that, but lets generalize).. and grade them on 1 being total shit, and 5 being pretty much as good as possible for the current time...
North America 5
Western Europe 5
Eastern Europe 3
Middle East and North Africa 1
Rest of Africa 1
North Korea 0
China 2
Rest of Asia 4
South America 2
Average of everywhere together = 2.3
Average of everywhere without U.S./Western Europe/Canada 1.85
Now, why the fuck would you want to live in a 2.3 society when you can live in a 4.0 or 5.0 society?
Math bro.
