"The rules of consistency of decisions and of efficiency in carrying them out in a socialist economy are exactly the same as those that govern the actual behavior of entrepreneurs on a purely competitive market. Competition forces entrepreneurs to act much as they would have to act were they managers of production in a socialist system. The fact that free competition tends to enforce rules of behavior similar to those in an ideal planned economy makes competition the pet idea of the economist. But if competition enforces the same rules of allocating resources as would have to be accepted in a rationally conducted socialist economy, what is the use of bothering about socialism? Why change the whole economic system if the same result can be attained within the present system, if only it could be forced to maintain the competitive standard? But the analogy between the allocation of resources in a competitive capitalist and a socialist economy is only a purely formal one. The formal principles are the same, but the actual allocation may be quite different."
