Marx is back

In the last 150 years of U.S. history, you can't point to a generation whose most active, radical layers have not been drawn to the ideas of Karl Marx.

Marx's Marxism is the theoretical product of his practical efforts to build a movement for change, and his observations of struggles taking place around him.

They're often called utopians, but Marx and Engels were the first to bring socialism down from the clouds and explain how it could be established in the real world.
