For decades, conservatives have relied on the same arguments when confronting socialism. Those of us who believe in free markets and individual liberty have leaned heavily on history and economics to make our case. We point to the Soviet Union, Communist China, Cuba, Venezuela, and other failed experiments, and we explain how socialism destroys prosperity, crushes innovation, rewards political favoritism, and concentrates power in the hands of politicians and bureaucrats.

All of that is true. It is also no longer enough.
