Taxes for Average Joe German are above 60 percent.
There is zero reason why the working class should ever expect anything more than a tiny 60 HP car (to share), and a 2 bedroom apartment.
Houses in Germany are outrageously priced.
Hitler had a program that gave married couples a modest suburban house with a small garden plot and orchard, with 25% of the mortgage forgiven for every child born (so four children and you are mortgage free!). You can see many of these houses on the outskirts of the cities, something like 1.5 million of them were built between 1933 and 1939. Some friends of mine live in one outside Stuttgart that the man's parents received through the program.
Probably the worst thing that happened to Germany in WWII was to lose 25% of her land to Poland, and to have 12 million Germans from the East expelled into the remainder of Germany, which had previously held around 55 million people. -25% in land and +20% in population is not a recipe for a reasonable housing market.
