Before and after *ovid. Before, companies were shameless about offering $25 / hr for highly skilled independent work, contractors and temp co's both.
You're quoting the after ovid market. There's more people on the sidewalk having lost what they had before, job, house, apt, but also getting those back by working for a living for it, has also gotten farther out of reach. 35 - 40 does not buy what it used to, especially if you expect electrical work is a middle class living. That would have been typically little job, little house, little car.
Guys at 40 / hr you'll see the gf drop them off for work. No car. Don't ask about the apt or house. You can see it on their faces before asking.
I've seen temp co's with an open call for *everyone* literally, but they had to work and a cut was made there. That was last year. This year Indeed job open ads are very way down. Job opens are cut way down. Normally a supply and demand issue.
Not today. The problem today is making a living (rent mortgage car payment) at the (higher) market rate. Guys with skills are in and out of work I see. If you cannot get there by working for it, that's the market incentive structure. You may be thinking in terms of separating wheat from chaff.
While you're doing that the larger structure of the market is making chaff out of everything throw into it.
