I'd like to see this but - not sure if it is already - adjusted by total pay. so # employed * average salary.

A -4.0% hit to cashiers may have less of an impact than -4.0% to lawyers or another category that is propping up the middle of the economy with spending.

It's the other way around. Cashier's spend their 4 percent, where's the lawyers probably save it. Though of course median salary for the two categories means 4 percent change is different in absolute dollars
