I don't know the real economic term, but I mean the concept of putting a cap on how much people can own, then tax the shyt out of anything over that limit. We got billionaires with so much money they're out buying stupid stuff. Who the fukk needs a yacht that looks like a damned US Navy destroyer???

I used to always think there was a practical limit to how much you could spend; you can only buy so many houses that you'll ever spend time in, drive so many cars, wear so many Rolexes, etc. But the mega rich will FIND a way to flaunt no matter how much you give them.
