I thought the topic was Switzerland, I got ?'em mixed up, as I am watching Mississippi Burning and posting simultaneously late at night. Well it was good for a chuckle, I could delete it all. However I have found specifics as to Sweden benefiting from the Nazis, but nowhere near to the same degree.
During the war, Sweden was openly pro-fascist. However, Sweden was one of the more cooperative countries of the neutrals. The high grade Swedish iron ore formed the basis of a strong and profitable connection between Sweden and the Nazis. The Nazis regarded this supply of ore as vital. So vital, in fact that the Nazis delayed the invasion of the Low Countries in order to invade Denmark and Norway first to protect the shipping route for the Swedish ore.
S & K bearings was another Swedish company that enjoyed a profitable relationship with the Nazis. S & K also presented a special problem for the United States, as the US was equally dependent upon S & K for bearings. S & K did its best in delaying production for war munitions in its US plants. Such a situation presented the Roosevelt administration with a dilemma. The US could impose sanctions on S & K, Sweden, or both. The sanctions would most likely result in a reprisal by S & K in further limiting the production of bearings and disrupt the production of war munitions. A second option for the administration would be to seize the plants for the duration of the war. Such a move would only further the charges of the rampant communism and socialism present in the administration by FDR's critics. The only other option was to allow S & K to continue with business as usual, which was the course followed. Regardless of who won the war, S & K was sure to win big by supplying both sides with bearings.

Sweden also profited from the Holocaust. It is known that Wallenberg's relatives made money converting Nazi gold into Swedish crowns and that Sweden provided iron ore and ball bearings to the Nazis. Swedish documents reveal that some Swedes actually sided with the Nazis and volunteered to fight for Hitler. Some Swedes were members of the Waffen SS and served in police battalions.
A committee was established by the Swedish government in 1997 to investigate the transfer of Nazi gold to Sweden during the war. It is reported that Sweden received 38 tons of gold from Nazi Germany (worth today US $430 million). Many Swedish companies, such as Ericsson, AGA and Hasselblad Cameras, as well as the country's paper and wood industries traded with Nazi Germany. Swedish jewelers bought stolen diamonds, which were smuggled into Sweden by civil servants working at the German legation in Stockholm.
