Hitler is always portrayed as having lifted Germany out of the post WWI economic crisis, spending massive amounts on building projects and secretly re-arming. Where did all of that money come from? It seems like 1930s Germany was doing better than the 1930s US, was that just propaganda?
There's a whole section on the wiki about Nazi economic policies. This post by /u/cfmonkey45 covers the extent to which Nazi policy 'fixed' the German economy. Another post by /u/Prufrock451 discusses the nature of their military spending. Hopefully you can find your answers in there!
