To take a contrarian view, maybe what is happening is that so many full-time boomer workers are retiring that all of the full-time positions they vacate can only be filled at a breakeven rate by the gen nexters.
Meanwhile, newly retired boomers will still work part-time and gig jobs so that is fomenting the growth in creation of the many part-time and gig positions; as firms can only create new positions under terms the available workers are willing to accept; and the retired boomers will not accept full-time employment.
So the Obama admin is taking a lot of heat for the 'quality' of jobs created under the time of their administration with criticism of part-time and gig work; but that might be just a result of the demographics and available worker preferences and was always beyond their control entirely.
If so, we may be closer to true full employment than those believing we are far from it are being led to believe; and any new significant Trump fiscal stimulus may not be well received at this point.
