It’s not dead but it’s a carrier of death.
I’m a little rusty on Johnny Keynes, but that era was riddled with commies/socialists/fascists, ? The head of the IMF at its creation was a Red, for just one example. Their goal was the destruction of capitalism - that is free markets, private property, human rights, etc.
To be fair, and what nobody ever mentions, ever, is that Keynes theory of deficit spending is predicated only on a balanced budget? The last time that happened if figures can believed, was somewhere around 1954.
Deficit spending is a recipe for the confiscation of wealth. Seems like Keynes theories were twisted at best, into a mechanism to bring ruin.
