I wonder if anyone ever said "Democracy would never work, just look at what happened to Athens".
Socialism and communism are relatively new ideas. While I don't believe communism is an effective form of government, it's still kind of silly to write it off so quickly.
There is a poem in Polish, it goes in fast and dirty translation: "Today you scare us with communists, just as years ago, you scared our fathers with the democrat name".
The more I study history, the more I see the great wheel of humanity. Communists now, Jews in the 40s, Muslims in the early middles ages, the barbaric Gauls before Christ was even born. It never stops. The people with wisdom die off leaving remnants of their culture and ideas while the next generations tries to piece it all together.
