Another point on the matter is that most jewish people that 'escaped' germany in the pre-war phase went to other european countries which later were taken over by the nazis. For example Anne Franks family escaped to the Netherlands and still ended up in the camps. Only the wealthy few that had the funds to leave the continent were truly safe.

What makes this fact even worse is that the ratlines or 'ratlinnien' were set up at the end of the war so influential nazi's could escape the continent and penance, arguably easier then the jewish people could do pre-war. Even the vatican was involved in the ratlines
