WASHINGTON (Reuters) – In normal times massive unemployment and a collapse in economic output would be tragic. This time, as the coronavirus cloisters millions of Americans and shuts down the U.S. economy, it should instead be saluted as an investment in public health that lays the groundwork for a rapid rebound. That is the view of St. Louis Federal Reserve President James Bullard, who argues that a potential $2.5 trillion hit coming to the economy is both necessary and manageable if officials move fast and keep it simple. It may seem an unconventional view in a moment of global anxiety, but Bullard argues the shutdown measures now being rolled out are essential to shortening the course of the pandemic. They must also be coupled with massive federal government support to sustain the population through its coming isolation and prime the economy to pick up where it left off.
