There is not a "labor shortage." There is a mismatch of job skills and a set of bad incentives as far back as the start of the pandemic. No one with contemporary job skills (be they technical or manual) is sitting on the sidelines. By this I mean there are no plumbers or electricians sitting on their asses, just as there are no .NET or JavaScript coders doing nothing. The people who are sitting on the sidelines have weak, infinitely fungible skills, and many have deluded themselves into believing they can live on gig economy scratch forever.
The bifurcation of the labor market into earners and scrapers is exacerbated by the Dem insistence on importing illegals into the country. All that does is dilute the market for unskilled labor, which describes most working-age DUmmies perfectly. The fact that so many older DUmmies whine incessantly about their hourly-paid jobs tells me that they never had contemporary job skills, or they were too busy smoking dope to keep up with job skills. This implies as well that they probably didn't save or invest, which means they have little to fall back on.
Ordinarily, I'd say, "too bad, so sad," but we have fallen into a weird place where even "Republican" admins think the answer to all problems is to print money and write checks. So all of these poor people that the government/education/entertainment complex created will be taken care of by someone, and that someone is (a) all of us, in the form of inflation, but also (b) anyone who worked and saved rather than putting on a fedora and pretending to be Howlin' Wolf so people on the internet will notice them.
Hard times are coming soon. Very hard. The only good thing about that will be that good people will be created, and they'll help usher in better times later. At which point, of course, those good times will create more effete, guitar-strumming, Cultural Studies, tattooed, tranny, drugged-out, work-avoiding freaks that will restart the cycle of misery we find ourselves in now.
