I’m not too convinced, especially when it comes to Keynesian regulatory policy –nobody wants more regulation unless it serves some kind of purpose. I’m also not convinced with this statement (emphasis mine):
After five years of Keynesian and other anti-market “remedies,” Europe overall is in recession
Europe definitely did not take any “Keynesian remedy”. I would rather call it a badly-implemented austerity program. One that ended up in: ↑T ↑G, T + G = ∞ , which might explain yesterday’s insane vote in Italy.

Politicians and bureaucrats want more regulation because it increases their power and makes citizens increasingly dependent upon government.
Keynesian advocates wouldn’t want a predatory government either, right?
They Keynesians in the US government sure do want predatory government. Their shrill advocates such as Krugman and Reich keep pushing for the expansion of government spending, regulation, and intrusion into the affairs of individuals and business.
