His essay doesn't convey even the smallest hint of what any alternatives may resemble - only a platitude is offered: "The guild tightens its grip when it should open its mind to new data sources, new analytics, new economic models, new communication strategies, and a new paradigm for policy."
The one clear idea is how "in bed" the Fed is with the financial industry:
(1) "[The Fed] appears in thrall to financial markets, and financial markets are in thrall to the Fed..."
(2) "A new inflation target ... would please the denizens of Wall Street who pine for still-looser Fed policy."
(3) "From the beginning of 2008 to the present, more than half of the increase in the value of the S&P 500 occurred on the day of Federal Open Market Committee decisions."
(4) "Long after the financial crisis, the Fed holds trillions of dollars of assets that would otherwise be in private hands."
(5) "...[I]ts compulsion to keep asset prices elevated..."
In the end, though, the only message that comes loud and clear is "inflation bad", but no mention of the apparent worldwide deflation that brought on the very idea of encouraging inflation per the "groupthink".
