Why Marxism doesn't work

Watching This video makes me realize just how unrealistic Marxism is.  Its not that Marxist are bad people, I fully believe that they truly have the people's best interests at heart, particularly poor people.  However, the Marxist version of reality, in my opinion, is wrong. That's why Stalinist/Leninist Soviet Union and Maoist China ended up the way they did.  In theory Marxism is great, in reality however it could never work, and this video proves why.

Was Marx Right All Along?

Is it just me, or has the U.S. recently sped up its race towards socialism?  Obviously not Soviet-style socialism, but modern E.U. style.  From the Great Depression through the Bush administration, we went from debating the New Deal to passing multiple stimulus' and bail outs during one administration, while at the same time funding programs such as unemployment, Social Security, welfare, food stamps, and a list of other re-distributional social programs.
