Why did these companies partner with Nazi Germany?

Several well-established American companies aided Nazi Germany during the Holocaust, directly profiting from the atrocities perpetrated against the Jewish People. These include well-known businesses like IBM, which supplied data processing systems to the Nazi regime, and Ford, whose German subsidiary produced military vehicles for the Wehrmacht. The majority of individuals involved in the decision to do business with Nazi Germany were motivated by greed rather than anti-semitism. The question remains whether or not these corporations should continue to be held responsible today for the role they played in the murder of Jews during World War II.
