Your belief that "there's always a tendency to avoid personal responsibility when things don't go well' is your personal opinion and says more about your personal view of the world. If this is true, why the increase in suicide, depression, anxiety. Why are American's the most stressed out population?
Ignoring the affects of American's economic system and the role it plays in our growing mental health issues is itself not mentally healthy. Blaming each of the millions of individuals for not thriving for personal failings in a system we control is sociopathic.
