In his review (collected in "The Present as History", 1953) Marxist Paul Sweezy joked that Hayek would have you believe that if there was an over-production of baby carriages, the central planners would then order the population to have more babies instead of simply warehousing the temporary excess of carriages and decreasing production for next year. The cybernetic arguments of Stafford Beer in his 1973 CBC Massey Lectures, "Designing Freedom" – that intelligent adaptive planning can increase freedom – are of interest in this regard, as is the technical work of Herbert A. Simon and Albert Ando on the dynamics of hierarchical nearly decomposable systems in economics – namely, that everything in such a system is not tightly coupled to everything else.
