Who would not say anything, but the Jews know how to live and build their country. Despite years of conflict with their neighbors, they are like outcasts all over the world and yet their standard of living is much better than in many countries around the world.
Even before the foundation of Israel, the Jews had some of the highest standards of living in the world. And despite the holocaust and the numerous wars, they were able to build their new country from scratch.
I think that the success of many Jews started the mechanism of repression. People are just jealous of Jews and their success. The Arabs are doing the same as Hitler. They simply have no strength to destroy Israel. However, this does not prevent the Palestinians EN masse to go to work in Israel.
