Economics discusses the margin, and the concept of marginal all the time. For example, the marginal worker is the one who loses his job, at a downtick in revenue.

Well, since the government response to the virus, over 26,000,000 people have lost their job.

It is not just one worker who occupied the role of marginal worker. It was over 26M workers (and counting).

The concept of margin also implies the concept of width: how wide is the margin? All those included within this finite space are at risk of loss of their job, business, etc.

And due to a number of factors, including decades of falling interest and margins, with rising net present value of all liabilities including debt and wages, the margin has grown quite wide indeed. And of course a months-long shutdown widens the margin much more than a week-long shutdown.

Perhaps 30% of the US economy (we shall see how big it is) was included in this wide margin. The fallout will be felt for many decades.
