Given the political climate in the US — with accusations of socialism flying left and right — it is fascinating that they were able to conceive and execute literal redistribution of farmland and that is has been held up as a exemplary example of successful reforms.
Perhaps there is more to the story, punishing the social class/monied interests that prosecuted the war?
There was considerable appetite for socialism immediately after the war, and the US officials of the early occupation were notably progressive (New Dealers, basically). As US-Soviet relations soured over the next 5 years, a lot of reforms were walked back or discarded, but some were obviously irreversible.
