>>15520th century communism is a total failure. They couldn't get everything right. The central planning was too abstract because they're totally oblivious to those problems. The planned economy system didn't work, couldn't adapt, didn't have quality control, didn't have quota control, bureaucratic intervention, etc. Because the whole system failed, The lower goons had to improvise all the time, but because of the politburo's obliviousness, it was for vain (see Kantorovich's dismissal). It was 'orderly' for the politburo, chaos for others.
I'm not implying that neoclassical 'bourgeois' economy works, because it doesn't. This is the second problem for us, for twenty-first century communists.
