“Jew estates” were used to train Jewish youngsters to be farmers so they could emigrate to a country other than Palestine. The Nazis did everything possible to help and encourage Jews to emigrate. Everything!
There was never a time when Jews were not free to leave Germany, at least well into the war when all movement by everybody was severely restricted.
The problem was that the Jews had nowhere to go. Palestine had limited capacity and no jobs, and it was a harsh environment compared to the climate and landscape in Germany.
No nation on earth would accept Jewish refugees from Germany. None! The Jews seemed convinced to the very end that their sheer numbers in the greater Germany area would ensure them a lasting place in society – eventually.
In the modern day, the same thing is happening to white people worldwide. The races of color have doomed us to extinction and we live in denial that such a horrific thing could ever happen.
