The countries where it freezes hard in the winter are the most successful? In the southern areas, like the equator countries, they are not so successful. I believe the very cold weather conditions over time cause an areas people to be more industrious.
Take an island country that also freezes hard in the winter and they will be so industrious they will dominate the world if allowed to. Just an observation.
