If we eliminate the private sector for one industry, it's not like the bernie left is going to stop there. They'll push for another industry to be destroyed by the government, and so on, until "the free market" looks like China's - a few private businesses are allowed so they can look capitalist, but everyone knows they're not actually capitalist (And it would not matter if we still elected our leaders - Socialism is an economic idea). The only reason the bernie left doesn't say this is because if they did so, the entire democratic party would suffer losses far worse than they did in 2010. We have to take a stand here, while capitalists have the advantage, to prevent the erosion of the capitalist values under which this country was founded and must keep to remain the greatest country in the world.
Nah, that's not accurate. These days socialists support the idea of worker-controlled industry in the form of cooperatives (think: market socialism) and these people are on the fringes.
Anyways, considering how strong China's economic performance is, that isn't much of a boogey-man these days, is it?
