The economy is doing super great and that is the problem. The old trick was to pump up the rates until unemployment increases and demand drops. They tried it and it's not working.
Sometimes this requires a reframing of what one’s talents are when applying for jobs outside what one might consider a normal window.
Also, I might recommend getting a recruiter to work for you to throw more mud on the wall so to speak.
The industry that wasn't affected by a large demographic of near retirees was technology. Because age discrimination was built into the culture. Not a lot of old programmers sticking around. They get RIFed right outta here. So while there is a shortage on teachers, nurses, trades, and police there is a surplus of junior and mid-career tech workers.
