Lately in a lot of media I’ve seen a trending comparison: the migrants and refugees and immigrants of today are compared with the Jewish immigrants and refugees of early 1900s and World War II.
They emphasize how the Jews of today are successful but were once immigrants given the opportunity to come here and work hard. They often mention how ships filled with Jews were sent back to Europe during the Holocaust and how those aboard were killed as a consequence.
To what extent is this comparison valid? Are there problems with it? Is it ever offensive? Are certain (mis)uses of the comparison problematic or misleading? What are the merits and pitfalls of this trendy comparison?
