An absolutely excellent article. My favorite quote:
The Marxist goal of seizing the state and using it to eliminate all oppression is an empty promise. Marx did not know how the state could actually bring this about, and neither have any of his followers. In fact, we now have many historical cases in which Marxists have seized the state: In Russia and Eastern Europe, China, North Korea, and Cambodia, Cuba and Venezuela. But nowhere has the Marxists’ attempt at a “revolutionary reconstitution of society” by the state been anything other than a parade of horrors. In every case, the Marxists themselves form a new class or group, using the power of the state to exploit and oppress other classes in the most extreme ways—up to and including repeated recourse to murdering millions of their own people. Yet for all this, utopia never comes and oppression never ends.
