This is a few weeks old, but I felt it is relevant here. Noticeably absent from the "speculation" as to the reasons fewer people in their 50's are working is the elephant in the room: Ageism. I gave up searching for work because it's painfully obvious my capability is not the issue. AARP has permanent support education for 50+ people trying to get hired.
All I hear about with respect to frustrations being unable to find a job is focused on the youngest, while it's the eldest that are being forced out at alarming rates. The worst part is we don't have any recovery path, and some of us are supporting adult children who can't find work.
We either navigated all the pratfalls life throws at us and have savings enough to "survive", or we didn't, and we become another near invisible member of the predominantly elder population of homeless standing by intersections hoping for a handout.
Next January possibly millions of over 50 people thrown out of work and unable to find any job (even minimum wage jobs) will lose their health coverage, since Medicaid begins requiring 20 hours per week of work to qualify.
We are well beyond "fearing dystopia" now. We've been living it for a decade, some would say longer.
Absolutely ageism. I recall applying for a job I was perfectly matched to. They might as well have just posted my resume for requirements. I happened to be 50 at the time. They made zero contact. One time is a fluke, but I kept getting ignored for jobs I was very well qualified to do. That happens a lot in the art field, and I'm sure many others. Young artists only want to work with young artists, even if the job itself is more production work than creative.
It's broader than ageism though, that's just a part of prejudice.
You are not the only one getting ghosted for jobs.
It takes hundreds of applications to get an interview these days. This is for most everyone regardless of qualifications.
You might not have even applied to a real job. There are literally countless "ghost jobs" out there. There is no job. They have zero intention of ever hiring anyone. See more: https://en.wikipedia.org/wiki/Ghost_job
