Is there strong evidence that widespread adversity like a recession increases mental illness? I would guess that those kinds of factors that affect everyone in your social group have a less negative effect mental health wise, as everyone around you is going through the same thing.

At least with measurable indicators of mental health crises like suicide rates, groups that are worst off by most socioeconomic measures tend to have lower suicide rates. For example, the black suicide rate in the US is less than half the white suicide rate and have been through Jim Crow laws and generally much lower SES. From what I've seen, the same is true when comparing across countries, with suicide rates being positively correlated with GDP and income.
