I'd rather have some Keynes than get pissed on with some 'trickle down' economics.

I would say, I'd bet nobody having an argument about economics here has actually read much Keynes, or anything about classical/neo-liberalism. It all just turns into "I recognize some word related to the right, so I'll virtue signal and keep hyping it." Or more, "I see a free market economy argument happening, I must jump in and comment because markets are from God and I must support".
