retire
Or go out on your own and start your own business. Any skills a person has, he / she can market. And any skills not currently possessed can be learned, then marketed. People need stuff. And they need services performed. The self-employed can tap into the average American’s love of convenience and “having someone do it for them”, vs. doing it themselves.
It’s no bed of roses. Nothing is. BUT . . . that person would then be able to reclaim his / her independence and self-confidence.
