The idea that the Nazis would take money for jews was unfortunatly a false one.
When you give a bribe to someone the person is supposed to do what you want, no matter what the law is. However the Nazis when they took bribes ostensibly to save a jew, they frequently killed the jew anyway or waiting a short time and killed that person. It was not a Bribe, but rather theft. Meaning they were trying to steal money from the jews to pay for the war. Especially in 1944 when the Nazis were almost bankrupt and losing the war. They needed money and supplies to continue to fight. They had no intention of saving Hungarian Jewery, but they had every intention of trying to steal money from the only jews who had any left (American Jewery) to continue the war.
Spain was not a destination for jews in 1939. Spain fought a brutal civil war in the 1930’s and was in ruins. They were in no position to take huge chunks of refugees at that time. Go do some research on the Spanish Civil War before making any claims Spain could take lots of refugees.
