bler144: 1) in many cases, the jobs aren't
where the potential employees are, and the startup cost of relocating is too steep for many employees (or employers, for that matter) to just move easily. The exception is basically middle- and upper- class post-college singles or DINK couples. Add kids into the mix and it's not just the cost that gets complicated but family.
So anyway, you have a problem that remote work simply can't solve in certain fields, and hasn't really worked as projected even in fields where remote work in theory should be going smashingly.
There's an angle i haven't thought of. I'm curious how deep this really goes, though.
2) Worker training - the U.S. economy has gotten very used to outsourcing its training costs onto the education sector, particularly higher ed but to a lesser extent also voc tech secondary. Externalized costs. Most companies don't see the competitive advantage to paying for their own training, which imo is short-sighted, but I'm not sure what it would take to shift that needle. It seems unlikely to emerge at least from the publicly traded corporate sector where their revenue/costs are heavily scrutinized every quarter for any blemish. And at least at first, this would appear as a blemish on their corporate filings/reports.
Right, which i think is particulary dangerous. From what i'm seeing on the job market, this is easily the biggest problem when it comes to "not enough skilled work." This outsourcing of training costs is highly problematic for the businesses: they want people to get trained (don't accept self-teaching), but on the flip side they won't provide the training. It used to be different, really, and companies would do the contract thing, but we're not seeing that, anymore. This is even happening with public sector jobs, as well. The term for this, btw, is "progressive credentialism," in that it's constantly progressively getting worse (as they try to also use this as a source for an intelligence test).
3) Salaries have been stagnant, particularly in certain income bands and job sectors. You can blame monopsony or corporate greed (from the left), or lazy workers who clearly all should have chosen to work as IP lawyers (from the right) but the money isn't there, esp. given that working does COST money (clothes, impact on meal planning/options, direct and indirect transportation costs, training, often equipment). Sometimes the decision to pass on a $12/hr job is quite rational.
I would disagree with your left-right comparison, but otherwise correct. I'm conservative, but i'm passing on $12/hr part-time jobs, even though i'm unemployed. If I can't pay the rent, feed a family, etc, why sacrifice my freedom? Do i work to live, or do i live to work?
4) Extending #3, in some areas, childcare is brutally expensive. In the short run it can absolutely be more affordable - and in some cases necessary - for working class parents to not work because the amount they can make is less than what the childcare would cost until the kids are school age.
This is very much a part of #3. It's been shown scientifically that children do not do well if both parents are working. Ideally you want a stay at home mother, but a stay at home father is better than both parents working. Now days, because of the cost of living, but the lack of wages (and i blame taxes and regulations for this), both parents must work, and if you don't have a child, you must still "shack up" with people to pay the rent. I know very few people who live alone, and usually they're on income adjusted housing and/or welfare programs, unless they're paid an astronomical amount of money per hour.
I could go on, but that's about all the energy I have for a Sunday afternoon.
Though I would clarify one thing you said - all unemployed people do show up in the unemployment reports, they just don't show up in the U3, which is the "official" rate that gets most of the press coverage. They do show up in other DOL unemployment reports, like the U5 (includes discouraged workers and "marginally attached" workers)/ U6 includes all above tiers + the "underemployed" involuntary part-time workforce).
I don't know for sure, but i'm relatively sure that i am not showing up on any of these.
