I don't know if it's caused by the earth's magnetic field, or something else. But it seems to me that there is a global tendency for all kinds of tensions (political, economic, social) to exist between geographic areas of the earth, north vs. south.

We had our own civil war in the US, north vs. south. Then the Korean war in which the north invaded the south.

(WW2 was an apparent anomaly, with just Latin America left out.) We are still bitter, some of us, about the north vs. south war in Indochina. (I say Indochina because it involved Cambodia and Laos, too.)

We had (have) Ireland vs. England. And there is even a north-south issue in Yemen at present, one of the most undeveloped inhabited countries on the planet.

Now, the EU members in the north are having their problems with the Greeks in the south. Other southern EU problems waiting in the wings are Spain, Portuga and Italy.

I am not very familiar with the demographic geography of the Balkans, but I'd bet that there was a north-south bias in the recent Balkan conflict that created Croatia and Serbia.

Where in the world does the consensus of experts say the best country to live in is? Why, Norway, of course. Next is Estonia.

Where I am living now, in the Philippines, there is a noticable (to me at least) north south issue. Like, people in Luzon (the north) say to me, "You live in Mindanao?" as they repress their feelings of incredulity and revulsion. I live just 6 degrees north of the equator, in the south.

Perhaps just for a change we should rotate the earth 180 degrees and make the south north and the north south. That would give the present southerners a break. It wouldn't change my situation much, except I'd then be 6 degrees south of the equator.
