My poor thought on Economy

Money always moves. It never stays at the same place forever. It always moves hands to another. Mr.X is rich today and Mr.Y is fighting heart and soul against poverty. But after a decade or more Mr.X's generation will become poor and after having a long time of poverty Mr.Y's generation will be rich . History has shown that how Asia or Africa was before and how they are now,and,how Europe or the Americans are now. This is the balance of Economy. Money never stays at some place forever .It moves for the balance of it's own demand. Now guess who control all these balances? Us? Mother nature? Who then?
