We can learn a lot about freedom by understanding how Marx wanted to establish communism. 

Six of his ten planks of establishing communism were:

"5. Centralization of credit in the hands of the state, by means of a national bank with state capital and an exclusive monopoly.

6. Centralization of the means of communication and transport in the hands of the state [by direct control of regulation of these sectors].

7. Extension of factories and instruments of production owned by the state....

8. ...Establishment of industrial armies [state supported labor unions]....

9. Combination of agriculture with manufacturing industries....

10. Free education for all children in public schools."

Sound familiar? 

This should be a serious concern to modern citizens who care about freedom. 

Every step the government takes in this direction is a step away from freedom.

In fairness, Marx did ask for, "Abolition of children's factory labor..." 

We should adopt good ideas no matter their source.
