“There were two types of Jews in 1933—optimists and pessimists”

There is a grim Jewish “joke” that says that when Adolf Hitler rose to power in Germany in 1933, there were two kinds of Jews—optimists and pessimists. The pessimists went into exile (usually to the United States and more specifically to New York City) and the optimists went to the gas chambers.
 
The origin of the joke is unknown, but it appears to have been told during the World War II period. The joke has appeared in several books published since 1990.

“Personally, I have faith in our community. I’m an optimist,” said Assouline, who intends to stay. “But whenever I say that, there’s always someone who reminds me, ‘In 1933, there were two types of Jews: the pessimists and the optimists. The pessimists left and went to the U.S. The optimists ended up in the death camps.’”
