"has metastasized into a collapse of the demand side"

"But there are clear signs that the collapse of economic activity has set in motion problems that will play out over many months, or maybe many years. If not contained, they could cause human misery on a mass scale and create lasting scars for families.
.
The fabric of the economy has been ripped, with damage done to millions of interconnections — between workers and employers, companies and their suppliers, borrowers and lenders. Both the historical evidence from severe economic crises and the data available today point to enormous delayed effects.
...
The economy is a gigantic machine in which one person’s consumption spending generates someone else’s income. The pandemic began by crushing the economy’s productive capacity — a shock to the supply side of the economy, as many types of business activity were shut down for public health concerns.
.
In normal times, when there is a negative supply shock (say, a year of drought that reduces agricultural crops, or new tariffs that make imports more expensive), the pain can be intense for people in sectors directly affected, yet the economy as a whole adjusts.
.
But this crisis is so large and so sudden that the usual adjustment mechanisms aren’t working very well.
.
The people losing their jobs because of shutdowns cannot easily find new ones, because so much of the economy is shuttered at the same time. The businesses in danger of closing have cut every possible expense
...
The result is that what started as a disruption to the supply side of the economy has metastasized into a collapse of the demand side
...
The demand shock, with lagged effects, is only beginning to hurt major segments of the economy, like sellers of capital goods that are experiencing plunging sales; state and local governments that are seeing tax revenues crater; and landlords who are seeing rent payments dry up."
