Once you shut down economic freedoms you inevitably have to shut down political freedoms. From John Stossel at townhall.com:

Last week, I reported on two myths about socialism. My new video covers three more.
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.
“Socialism always becomes authoritarian?” I ask.
“Everywhere you try socialism, that’s what you get,” he replies. “It’s hard to exercise political freedom if you don’t have economic freedoms. If you’re dependent upon the state for your livelihood, you lose your ability to use your voice to oppose (the state) because you can be punished.
