Is Mental Distress Caused by Social Structures?

The more unequal a society you live in, the more likely you are to become mentally distressed. But that's not where all mental distress comes from - it just isn't. So i guess i'm a little bit wary of totally agreeing with that position. You know, people go through stuff that happen in their families, and stuff that they see an stuff that they witness,. which are dramatic but aren't as wrapped up with structural and societa issues as other things like capitalism is distressing or patriarch is distressing.
