A self sufficient people. They are blamed for mostly everything bad that ever happened ever because Jews are easy scapegoats.
An example would be in the middle ages when the Bubonic Plague (Black Plague) was rampant Jews were the only demographic that wasn't getting it due to the fact that all Jews living where the plague was lived in close knit healthy communities differing from the peasants living in squalor usually getting it. That of course was blamed on the Jews.
Another example would be the Holocaust. Hitler was a pathetic man with one testicle and hate in his heart. He decided to take out his anger on the Jews, gays, gypsies and others by winning the hearts of the easily impressed German populace with his moderate speaking skills. Jews did nothing wrong to anybody and everyone smart knows this.
"Awe man I failed math for the year, it must be that slimy Jew David Goldstein's fault.."
Ignorant man 1: "You know that Jew family across the street?"
Ignorant man 2: "Yeah they seem like nice people.. But they are plotting our downfall as we speak.."
