I agree with you. Even in recent decades when aspect of society weren’t very different depression levels were lower than today. It’s a massive conglomeration of things that is really difficult to point to any one aspect. One thing I think about in relation to the rise of mental disorders is all of the environmental pollutants from chemical usage in a variety of products. There’s so many dangerous pollutants we know of, but yet still many more we don’t have a great understanding of but still pump out in high quantities. But, trying to change society is difficult and this could help many people.
