Modern Monetary Theory Isn’t the Future. It’s Here Now.

The infrastructure act signed into law last week marked a defeat for the faction of progressive economists in ascendancy in 2020. For these advocates of modern monetary theory, the insistence by both political parties that all the $550 billion of new spending be matched by offsetting revenue, known as “payfors,” goes against their belief that money is merely a tool for government.

This is a temporary rhetorical setback. The reality is that MMT’s ideas have insinuated themselves deep into government, central banking and even Wall Street—and the infrastructure act is in fact deficit-financed anyway.
