What if instead of the Nazis with their focus on lebensraum by conquest, another fascist movement comes to power that instead seeks to greatly increase ethnic German immigration while simultaneously expelling "undesirables" ( Jews, Gypsies, etc.). They still want the territories lost in WWI and are terrified of the Soviet menace, so expansion of the military is a must, if perhaps not on the same scale as the Nazis. What incentives can be offered to attract ethnic German immigration and where would most of these immigrants come from? Besides the armed forces and the munitions industry, how can these extra bodies be put to work in a country suffering a depression?
