Except that every economy north of Somalia is planned. The question is how much planning. It is useless to discuss the matter in terms of binary caricatures, everyone east of Stalin knows perfectly well that the state cannot and should not attempt to make every economic decision – dunno, who is left on the planet who does not know it? Kim, perhaps? Conversely the TFM fundamentalists have never managed to produce a working instantiation of their church – the best we can do is Somalia, tho even they have resurrected a government.
Nuts, the commies at least tried their theories, the TFMers are content with pretending that their just-so stories would work in spite of the fact that every market that has ever been formed – again, above the level of Somalia – has immediately sought out regulation of itself. Markets form in the town, where the local lord provides a standardized coinage and protects you from being robbed outright by your ‘customers’. TFM is in fact bad for business. Every society since the first city states have understood this. The Romans made a science of it. The only real question is ‘how much regulation’.
That’s why centrists are always right, because we don’t have an answer. We are always looking for the sweet spot between too much and not enough and that spot is never found exactly – close is as good as it gets. The rational left will and should always say: ‘more!’ and the rational right will and should always say: ‘less!’ and we haggle over it and come up with something sensible.
