Brazil’s pension system has a unique problem. Young women marry men old enough to be there grandfathers so that they can lay claim to their pensions when they die. The law in Brazil allows the spouses of deceased workers to receive almost their entire pension for the rest of their lives. And If the spouse remarries the pension does not stop! The only catch would be if the older partner lasts longer on earth than what was originally assumed when they got married. As with everything in economics assumptions are the key.
