It's not my fault the East Germans chose the Soviet model so I hardly think it's fair to suggest I came up with a false dichotomy to prove a point.
One half of the country chose the soviet command economy model, the other half chose to pursue an Austrian model. One half did immeasurably better than the other half. Those are the facts.
You can compare and contrast post-war West Germany and Great Britain if you like - the latter made great strides towards a more socialist governance probably as a direct result of the largely increased Government functions during the war, and the rise of those who thought that centrally planned economies would do better.
The point of bringing up West Germany is that the country prospered as a result of the liberal economic policies introduced in the immediate post-war period, both absolutely and relative against their East German counterparts, although the differences were small in the early years. It would be foolish to suggest that this is entirely down to the policy choices - all growth from zero looks impressive - however, it certainly did no harm and a lot of good.
