What I think is best for people's mental health is individualism WITH a strong sense of community. I've always believed our needs and traits have to be in balance, and that this balance is going to look a little different from one person to the next.

Mental illness seems to be front and center in people's minds due to modern media. There's just more information out there, more readily available 24/7. I don't know if mental illness is more or less prevalent than it was earlier in human history.
