Because they profit from mutual trade.Rankao post=18.74687.845221 said:So why does Joseph in New York state, have to pay for the Health care of some high school drop out in Alabama (the state I live in.) There's almost no relationship to him and in most cases you really never depend on him.
Because they share a common culture.
Because it's quite possible that the high-school drop-out is Joe's cousin or brother-in-law or childhood friend.
Because one day, either one of those guys might go to war on the other guy's behalf.
