BUT, the data is highly skewed if you look at income. [also 1] The worst paid workers also have much less paid sick leave. Only 45% of the lowest 25% income group do. According to the BLS there were 130 million workers in 2019, thus leaving roughly 15 million people (130 x 0.25 x 0.45) without paid sick leave and likely without the financial means to go on unpaid sick leave or get medical help (like testing).
Also, the average paid sick leave varies between 6-10 (working) days. Suggested quarantine is 14 days. [2] Only 3% of workers have sick days "as needed". [3] This supports the argument that these circumstances make matters worse. I tend to agree to the general argument.
