> The "it" being that the issue wasn't that they - and the future potential partners - didn't have a day job.
Maybe not. However,
- If they haven't been able to identify what the real issue _is_, AND
- Avoiding dating people that don't have a day job limits (or completely prevents) dating people that do have the real issue, AND
- Avoiding said people doesn't limit the number of available people to date below a reasonable threshold, THEN
- Using "doesn't have a day job" as a filter seems to be a reasonable compromise for them.
Sure, it may prevent them from finding the "best" match, since there could be a person without a job that doesn't exhibit the real problem. But it's possible that removing that filter would cause so much wasted time (on dates with bad matches) that the odds of meeting a good match, nonetheless the best match, as significantly diminished (as is QoL).
