The end might be noble, but I think this is the worst way to reach it. I agree that there is a place for decency in the society, but making laws based on what a majority deems "shameless" is a characteristic of the past centuries which I am glad we have somewhat get rid of. So I think that trying to make "politically acceptable" a ban via the use of morality is alike opening Pandora's Box.
   Secondly, flaunting one's wealth is a quite innate and resistant human characteristic and all the smptuary laws   and all the monuments of literature written against it have succeeded little.
