Intellectuals and politicians often try to verbally summarize or justify conventional thinking in pithy ways. Milton Friedman (in 1965) and Richard Nixon (in 1971) both said different versions of the phrase "we are all Keynesians now."
John Maynard Keynes, one of the most famous economists of all time, supported deficit spending and government manipulation of economic activity. Friedman and Nixon were describing the thoughts behind the implementation of Great Society redistribution programs and an inflationary monetary policy designed to offset the cost of those programs.
If economic policy was Keynesian in the 1960s and 1970s, as policymakers stopped believing in free markets, we are certainly all Keynesians now. COVID spending and monetary policy are a clear continuation of this economic thinking.
It all began in 2008, when the Bush and Obama Administration combined spent $1.5 trillion of taxpayer money to "rescue" the economy and the Federal Reserve started Quantitative Easing. That blueprint of policy response to the Panic of 2008 was used to respond to COVID shutdowns. This time the Federal Government borrowed at least $5 trillion to spend and the Fed increased its balance sheet by over $4.5 trillion.
As a result of the Keynesian policies of the 1970s, the U.S. experienced stagflation (slow growth and high inflation) – with both unemployment and inflation peaking in the double digits. Right now, inflation is 7.9% and the unemployment rate is 3.6%. So while inflation is clearly here, signs of stagflation are harder to find.
That doesn't mean economic growth isn't being impacted. There are multiple forces to analyze and untangle to understand everything that lockdowns and government largesse have done.
