Keynes is awfully misunderstood.
Many today think he's the devil incarnate for coming up with this notion of government spending to save the macroeconomy (ostensibly to make us all slaves, etc.). If, however, you've read any of Keynes' books you'd understand his theories were tried simply because we were out of ideas. He didn't think any of this stuff would work, and it was just a last ditch effort. Furthermore, even he would admit that we we see today is not really Keynesian theory in action; it's become so bastardized from what he advanced, I'm not sure we can call it Keynesian theory any longer. For starters, he would have advocated saving money during expansionary times. We never did that. There are other modern diversions from traditional Keynesian theory. I'll leave it up to the reader to continue down that path.
I lean heavily Austrian School, for one main reason: human beings are rational actors and will act in their own best interest, the invisible hand of government notwithstanding.
