I think it's a poor choice of words on my part, Gordon. Rather than a problem it should be a 'situation' , which could include wants/desires as well as, or as substitute for, a problem on one side or the other.

On the other hand, if one wants more, or doesn't have what they desire or need and someone else has it, it can be a problem for them so... Ah, well, same thing, different way of expressing it, that's all.
