Do you think it's a viable system? If so, why? I think it's the most stupid idea to just discard the whole social structure overall. Also, give reasons to discard it as a political "system".
Consider a typical commie-Jew. There is nothing wrong with feeding him to lions at the Colosseum, else you'll get something like the revolution of 1917 with 20 millions dead (including teachers and scientists). I.e. the more Jews you execute at Colosseum, the less is the probability of revolution and the Dark Ages.
