Myth No. 3: Socialism works if it's "democratic."

As the Democratic Socialists of America put it, "Society should be run democratically -- to meet public needs, not to make profits for a few."

Sounds nice. If socialists are elected, then we'll have a more just society.

But Venezuela's socialists were elected.

"They can start off democratically elected," says economist Ben Powell, director of the Free Market Institute at Texas Tech, but "once they centralize control over the economy, it becomes impossible to 'un-elect' them."

Hugo Chavez was elected but became an authoritarian who chose his successor, Nicolas Maduro. Maduro now gets "elected," by having opponents arrested and "ordering state employees to vote for him or they lose their job," says Powell.
