The chart above is from Axios.com. It shows the percentage of jobs that are vulnerable (will be laid off or fired) due to the current Coronavirus epidemic.
As is usual, the workers who can least afford it are the ones being hit the hardest economically in the Coronavirus shutdown. That's usually what happens in an economic disaster in a capitalist country like ours.
About 77.4% of those making $20-$25k a year are vulnerable to being laid off, and the same is true of those making $25-$30k (about 55.6%). And those who keep their jobs are in "essential" workplaces (like grocery stores) where they expose themselves to the virus on a daily basis.
Far smaller percentages of those making over $40k a year are vulnerable to losing their jobs. Many of them are able to socially-distance by working from their home.
