I'm still trying to find my ways around US political terminology...
So "socialism" is anything remotely related to the public or government, "central planning" now seems to be any trace of state-wide coordination.
Look, sometimes coordination makes sense from technical and logistical point of view.
Capitalism won with Marxism because it was pragmatic and adopted any ideas that worked. Now if you reject any ideas because they "don't belong", it's simply dogmatic, not pragmatic.
