As a percentage of population, full time in Nov 2020 remains in the basement digging holes at 47.6%, reminiscent of the historic lows pre-Reagan and the double Reagan recessions of the early 1980s.
Full-time never recovered after the Great Financial Crisis of 2008, if you mean a return to pre-GFC1 levels. Under Obama and continuing under Trump full time after eight long years finally clawed its way up to 50.4% in 2019 on an average annual basis, only to be felled again by a lousing, stinking virus.
But don't make the mistake of blaming the virus. Conditions were long too weak to support pre-GFC1 levels of full time employment. Contrast this with the vigor of the Reagan/Bush surge in which full time went from 47.3% to 52.2% in just six years.
That missing vigor is the irreducible fact of the present economic malaise now in its twelfth year which very few acknowledge let alone understand.
