It was heavy American/Allied investment in West Germany that brought the nation into its status of power and wealth that has lasted into current times. Hitler had nothing to do with it...
Maybe it was all in his master plan. Maybe WWII was really just a multi-million life scheme to make Germany an economic powerhouse...
Heh, just kidding. In his last days Hitler wanted to sabotage all of Germany so that Stalin couldn't get any resources. Luckily, he was unconvinced...
