Avoiding the war with Poland will ruin the German-Soviet non-aggression pact - because the Soviets are going to invade Poland soon anyway. Therefore, extensive and very expensive fortification program on Polish border would be mandatory. Well, the Germany in 1939 was already pretty much cornered in the political sense (as they perceived) - what`s why they did the high-risk moves like invasion of Poland and France 1939-1940 IOTL. With siege mentality, talking about any economic development is nearly sure way to lead to government collapse.
If Goering would ask me to heal the overheated German economy..i will desert to England or United States. Too silly order. Germany at that point needed a suspension of normal economic mechanisms - a declaration of the state of emergency and a frantic military production to deter or at least delay Soviet Union threat.
