Probably many nuances to this question, but there is some literature out there indicating increased income is associated with increased suicide risk. One case control series reported in BMJ in a relatively large sample (~1500) found that "people with a history of mental illness and a high income are at greater risk of committing suicide than their lower income counterparts. This may be because richer people with a mental disorder feel more shameful, vulnerable, and stigmatised." http://www.bmj.com/content/322/7282/0.7.full http://www.bmj.com/content/322/7282/0.7.full From the paper: "In contrast to findings in the general population, the suicide risk for patients admitted to hospital with a mental illness fell significantly with decreasing income (P=0.0001)...In the adjusted analyses, a similar but less pronounced pattern was found in people who had never been admitted to hospital with a psychiatric disorder." http://www.bmj.com/content/322/7282/334.1.full http://www.bmj.com/content/322/7282/334.1.full
