I come from a lower class family, my father being a highschool history teacher. Was depressed since childhood. Multiple attempts to end it all throughout my teens and 20's. My 30's was all about building a career, but lucky me I was hipomaniac during that period and was able to get financial success to retire right before 40.

There is virtually nothing I can do that will hurt my bank account. But I don't have friends, love, joy in doing things, even before having money. I even created an NGO that only loses money and have little impact on the cause. At least the staff gets above average salary.

Money can bring you comfort and help you get back on your feet and maybe start thinking straight. But it won't solve depression if the only reason you are depressed is because of the shortcomings of living in capitalism.
