Skull and Bones
Another sure way to gain wealth is to marry into the Rothschilds (Red Shields) but that is not possible because you have to either 'interbreed' (however they changed that rule in the late 1800's) or you have to be already extremely wealthy. Or you could ask to borrow some of the worlds entire gold supply from the Vatican (around 10% of the worlds supply is owned by the Catholic church). That still doesnt top he Rothschild gold that is stashed in secret vaults globally, so much that guestimates put the value as high as, wait for it, $50 trillion. Problem is that they are immune to law, audits, and accountabilty - they are the law.
