"Antisemitism is the socialism of fools" (German: "Der Antisemitismus ist der Sozialismus der dummen Kerle") is a phrase denouncing the notion that Jewish "wealth" or "power" is the root of social injustice.
[1] According to British historian Richard Evans, the phrase was likely coined by Austrian left-liberal politician Ferdinand Kronawetter, but is often attributed to German social democrat August Bebel and occasionally to Karl Marx.
[2] By the 1890s, the expression was widely used among German social democrats.
[3] Neoconservative philosopher Leo Strauss argued that Soviet leader Joseph Stalin may have believed that, because fools were numerous, a "socialism of fools" would be advantageous.
Strauss suggested that Stalin deliberately fostered antisemitism for this reason.
