Nazi Germany was generally willing to kill and steal from its victims (especially during the war) rather than accept bribes for escape.

This may have happened some of the time, but everything I read suggests it was the exception and not the rule.

The reason Jews did not emigrate out of Germany during the 30s was that Germany had a big foreign balance problem, and managed tight government control over allocation of foreign currency. Jews (and Germans) could not convert their Reichsmarks to any other currency, either in Germany or out of it, and so they were less willing to leave. And no other country was willing to take them in in large numbers (since they would be poor refugees). This continued during the war in the West European countries conquered by Germany. (Ref: Wages of Destruction, Adam Tooze)

Later, all Jewish property was expropriated and the Jews sent to camps, so there was no more room for bribes - the Jews had nothing to offer since the Nazis took what they wanted by force.
