Yes, seriously. Every time I've had a wealthy character he always took it away. One time i was playing a billionaire batman type and he said I owed the IRS billions of dollars in back taxes for not paying them for years on end. My character ended up a homeless bum.
Meanwhile back at the former Batcave, the World Workers Union meets in their new headquarters, played by the guy on the other side of the table who takes advantage of the DM's personal foibles.
Did anybody ever try to do that?
