Imperialist core entry level jobs have been replaced with outsourcing for the working class and internships for the wealthy.
The lack of entry level jobs means that recent graduates are not hired because they are expected to know in advance how to behave in the workplace rather than being trained when they begin working.
Actually as many as 1-in-3 job listings are fake, because this allows companies to claim they are "actively recruiting and growing" even when they aren't, which looks good to investors and can lead to government benefits as well.
In the US, hiring several part time jobs allows companies to save about 30% on benefits compared to hiring one full time job. This is directly because of the US's predatory healthcare system and lack of the worker protections common in other imperialist core economies.
The US minimum wage has been static for my entire adult life, in part because efforts to pin the minimum wage to cost of living metrics are constantly stonewalled by wealthy political groups.
The US labor participation rate is around 80% of abled adults, which yes, does mean about 20% of abled adults are not working, but perhaps much more damningly, this is actually very high participation compared to a lot of US history, and yet the cost of living and pay are so mismatched that quality of life is reaching impressive lows.
Masters degrees are being devalued as a consequence of the prior devaluation of Bachelors, that itself caused by the destruction and devaluation of compulsory public schooling in the US. This combines with the absence of entry level positions in deeply fraught ways.
I am unable to corroborate the claim that US job searches average greater than a year. However they do average well over 7 months, and the US's notoriously spiteful and underpaying unemployment system cuts off support much sooner than that. If you can even get unemployment support in the first place.
And finally, yes, 75% of completed and successful applications will be automatically rejected by machines without human oversight. That's for complete applications on the company's own site with resumes attached. Just plain resumes, and applications completed on third party sites like Indeed, have much worse numbers than even that.
