This is just an old repeat of European history. When a country was in economic trouble, they always invited the Jews back, so that particular country became prosperous again. Once the Jews also became influential & prosperous, they were expelled & their wealth stolen by the country rulers. Then once these countries became basket cases again, guess what, they invited the Jews back again & so the viscious cycle continued. Read history & see for yourselves. Kind of sick mentality.
