On being the right size (1928)
This is really an argument against socialism as the communists tried to implement it. Where the state nationalizes every industry and all workers become employed by the state which plans everything centrally. Most socialists have moved beyond that model and would instead prefer to see a system of enterprise that uses co-op's instead of privately or publicly owned business. Some industries would probably be nationalized or socialized, but not much more than already is in the best parts of Europe. The main idea is to make the enterprises benefit those who do the actual work and also make them accountable to those people and their communities. The main problem with capitalism is that someone other than the people doing the work get to decide how the work is done and how to spend the surplus of value that work generates. If the workers decided these things they would never vote to outsource their own jobs and would rarely choose to pollute their own communities. They wouldn't vote to reward a tiny minority with a fortune while they pay themselves poverty wages.
