Economics is a scam. Keynesian vs Austrian is nothing more than a distraction for the plebs to argue over.  

We live in an oligarchy. The oligarchs do whatever they want. They don't give a shit if you want to use labels like Keynesian or Austrian, they are meaningless. 

Nation states don't choose between Keynesian or Austrian economics.

Nation states do what they are told to do by the oligarchs that paid to put them in power.  

I bet your 401k is invested with the very oligarchs you're indirectly raging against.
