Source of wealth for Obama and his mother: Obama’s grandmother Madelyn Dunham was vice president of the largest bank in Hawaii.
And Obama’s mother worked for Tiny Tim Geithner’s father in Indonesia.
This is a key piece of what was a huge puzzle for me. In the time during which 0bama was born, air travel was expensive and infrequent. It would have been extremely unlikely for him to have been born overseas as his mother, as an 18 year old, would have been unable to afford the air fares. With an affluent, indulgent grandma, it would have been much more possible.
