How will the state decide what to tell them to do? That's the real problem of socialism.
There's no way a socialist government can calculate and try to figure out who do we send aside, how many people, what price do we set, who's going to carry out the garbage, how many people should carry out the garbage.
There's no way the socialist government can calculate because, as Mises pointed out, there's no free price system, there's no private ownership of the means of production by definition, and therefore there's no property titles, there's no free market in property titles.
There's no way to set up a real-price system.
There's no way a socialist government can calculate.
It's even going to make chaos.
