A. Yes. Plus selling to the Wehrmacht ("war is a racket"), often with forced labour - or both, first stealing from Jews then selling to the Wehrmacht (like the current owners of BMW, ancestors sold to the Wehrmacht, profited from forced laber and additionally stole from Jews [1]). In communist East Germany Jews even couldn't get back their assets after the war, because Jews where "capitalists".

  B. The vast majority of Germans profited from stealing from Jews (see book "Hitlers Volksstaat"), e.g. Germany was out of money before Kristallnacht and Jews had to pay 1 billion Reichsmark after the progroms, which helped the German state. Also jewish furniture etc. was auctioned off to all Germans - people too often only talk about arts and houses.

[1] The Quandts already were rich selling to the Prussian army, then during hyper-inflation of the economic crisis bought struggling companies, then "bought" companies from Jews who were forced to sell, then used forced labour in their companies, sold to the Wehrmacht, after WW2 got everything back and the debt they accumulated to buy all of that had evaporated because of the war. Today they own large chunks of BMW for example.
