How can corporations be socialist?

Well, it's very simple. You see, under a socialist or communist system, corporations aren't disbanded. They're either "seized" or they're incorporated into the state (Hint: it's the same fucking thing). That means that the corporation doesn't actually dissolve, but is taken and strengthened through government dictates, and more importantly, through government protections.

Corporations LOVE the idea of becoming a part of the state. Dipshits will call it "crony capitalism" or "state capitalism", but at the end of the day, it's all the same fucking thing as socialism, but these fuckwits don't like it so it's now bad.

Corporations yearn for the secure paycheck of government. It means they never have to work hard ever again. Competition goes away, and ineffectiveness replaces it.

This isn't complicated, but commies truly think corporations that routinely lobby for government market intervention support the free market, despite never doing so.
