John Maynard Keynes

John Maynard Keynes was, to put it mildly, not Jewish. Born into an academic Cambridge family, his lineage was thoroughly British, tracing back centuries without a single matzo ball in sight. He was educated at Eton and King's College, Cambridge, cementing his place in the English establishment long before he started telling governments how to fix their economies.

Keynesian economics, which advocated for government intervention to stabilize economies, became the dominant paradigm for decades. His magnum opus, "The General Theory of Employment, Interest and Money," basically gave every finance minister permission to print money during a downturn, a concept some might argue has been enthusiastically — and perhaps excessively — adopted worldwide.

While his economic theories are still debated, his influence is undeniable. He was also a prominent member of the Bloomsbury Group, an intellectual circle known for its unconventional lifestyles and rejection of Victorian prudishness. So, while not Jewish, he certainly knew how to stir the pot, both economically and socially.
