You're getting at what's known as rotten life syndrome[1]. The themes are consistent across every demographic. When someone is underemployed, overworked, under housed, impoverished, starving, a victim of crime/persecution, etc then they will manifest the symptoms of various mental illnesses depending on what's going wrong in their life. Therapy cannot be useful if the basic life of a person is unstable. Yet these people are told they aren't working hard enough, they deserve what they get, etc. It's absolutely ridiculous. We have the means the house, clothe, feed, and care for everyone. Our electorate has, and probably will, continue to get away with, misappropriating these resources for their own gain, at the cost of countless human lives.
