Because Socialism worked so well in the USSR.

Over the weekend, a self-proclaimed “Marxist” and “Revolutionary Socialist” showed up at a pro-union rally (reportedly one of the ones sponsored by Moveon.org and Van Jones) in Dallas. Not only was he there, but he was also leading the chanting. Such gems as “No war but class war!” and “They say cut back we say fight back!” flowed from the lips of the protesters.
