Blood is thicker than water, as they say. However, perhaps it should be added "but money is thicker than both." Particularly if the blood is blue, it would appear.
The truth is, a number of American dynastic families might best be described as "rich, famous -- and feuding." Whether it's Grandma cutting off the heirs, or the heirs allegedly abusing Grandma, there's plenty of evidence that money can't buy a happy home -- no matter how many you own. In fact, it may be the cause of the discord. In Ethiopia, two rich families who have a common business falls in a feud that destroys lives of others. Asnake imports illegal items to the country while Mesfin tries to stop him. In between people die and suffer.
