Could you please give an example of this actually happening? If a government actually controls the business, then it's not workers who control it, it's the government, and you've merely replaced one set of oligarchy controlling government (capitalists, currently) with a separate elite oligarchy of insider government officials who protect each other (the nomenklatura, a.k.a. The Party, whether the Communist Party or the Democratic Party). True worker ownership means libertarianism: Minimize government, and encourage people to work only with truly worker-owned businesses.
