From what I've read the Bush family is SUPER rich now. HW has been involved in the CIA and specifically in it's drug running for decades. He was responsible for the Iran-Contra stuff and mostly the cocaine coming back from central America. They own so much land in Argentina that there they are known as the Argentinian Rockefellers.
most people don’t know that Bar was an heiress. I can’t remember what company her family owned but she is supposedly from old money.
