Isn't it strange lately? ㄷㄷ Why is the South always wealthier than the North?

Why is it that the South is wealthier than the North? ㄷㄷ
South Korea is wealthier than North Korea,
Gangnam is wealthier than Gangbuk,
Southern Gyeonggi is wealthier than Northern Gyeonggi,
and even in Germany, West Germany (South) was wealthier than East Germany.
I don't believe in God, but every time I see things like this, I wonder if a God exists as if there were a law of nature.
