Thanks. I did some research on that book. The 'economic calculation problem' seems to be the main point. I disagree that market forces are the only way to price goods and services. Why can't goods be priced that factor in the aspect of supply and demand, but also factor in the cost of offering those goods and services, both the immediate cost and the cost to the environment? It doesn't seem like an impossible problem, just that it takes deliberate effort by the state.

Note that in open socialism goods and services (including food, clothing etc.) are priced.

I generally agree that around 100 years ago when 'Socialism: An Economic and Sociological Analysis' was written socialism was difficult to impossible. Now with modern technology I think that it is possible and has less problems than capitalism.

Is there some key flaw in socialism that you think prevents it from being viable?
