Are you really that obtuse? I write my CV. It has 20+ years of experience plus degree from my University. Simple math not your strong point perhaps?
If you have 20+ years of experience on your CV it's a shit CV. Why would anyone hiring care what you were doing over 20 years ago? I'm wondering what else was wrong with it that you didn't get a single response in 2 years of trying. Were you including unique cover letters? Where were you finding the jobs you were applying to? Did you try going through a recruiter?

BTW, I find it puzzling you are focusing specifically on my perceived failure in the job market rather than the topic of the original post.
