Definitely a combo of Both (Score 1)

I have a second job because I'm poor, but many of the "elders" seem to be split between need and want. One gentleman I work with was screwed out of his retirement by a scammer promising him a timeshare in Florida. A couple others work for extra spending cash and to remain active. Many of these employees become great friends quickly, remember as we age we loose a lot of our friends, and it becomes a great social scene.
