Rathenau was a natural central planner with an eye for economic detail. He encouraged free traders, was honestly unrepentant believing in the efficacy of "preparedness and directional efficiency". AEG was influential: his colleague Wichard von Moellendorff was appointed as Undersecretary of the Reich Economy Office; for a time in July 1919 they worked closely for Weimar with republican Rudolf Wissell. But Hindenburg's technocratic rational economic Programme was borrowed; while Rathenau, being democratic, warned against short-termism. Berlin's March Days was a consequence of the internal struggle between Finance and Economic ministries. On 20 February 1919 he proposed workers councils "which had already been explained in his writings". The plan for a Socialist League of nations was overtly pro-Union mocked as the "Paris League" – a throwback to the Second Communist International – they challenged openly for democratic ideas. But a rapprochement with Soviet Union was inspired by Rathenau; it tried to prevent an expansive 'Greater Germany'.
