To Conservatives on Yahoo Answers, what do you dislike about Marxist Theory?

I don't know a lot about Marxist Theory.  I understand the USSR attempted to use some of its ideas and someone from there told me that under capitalism, greed increases productivity because people are greedy for money, and under socialism greed decreases productivity because people are greedy with their time.

There are some others who seem to have something against Marxism:“If anything is certain, it is that I myself am not a Marxist." - by Karl Marx in a letter about the peculiar 'Marxism' which arose in France 1882

I didn't take the time to find the quote where Marx says something like socialism only works correctly if everyone subject to it wants to be subject to it. 

I don't like it when a common citizen cannot tell the government. "No, you are in the wrong. And we will go to court about it." A socialist government, to me, is just pre-communism. That is where government has all the rights, including what you think you own. Your property is gone if the socialist government decides, "It is the will of the people." Socialism, sucks. It starts with good intentions, and then the money dries up. Then the bodies start to pile up.

This is what socialism turns into.

I'm a Democrat. But, I don't agree with Marxism. And Marxism/Communism has never been reached. Someone always wants control. The laborers in "Communist" countries do not have equal ownership in the companies they labor for. 

It's all fine and dandy until people try to escape. Then the barbed wire and machinegun towers come out

im not conservative but sadly marxism wont work because humans tend to be selfish scumbags 

It's not capitalism.  It's Marxist.

Our side.  Right or wrong.
