I'm a good developer at a good job and not that old. A few years ago I was in transition between a several-year volunteering engagement and work in the private sector, and the job search took a while. I got very few interviews at the time. I would have been an asset to any decent employer that hired me. I do not think the resumes I submitted were junk.
There appear to be structural changes underway that are making the job market volatile for a range of people, especially the long-term unemployed. I am not sure where it is all heading.
