I applaud mission creep. When most problems are labeled mental illnesses, we can unstigmatized psychiatry and easily get everyone the help they need.
You can spend a lifetime "fixing" all your problems, or you can get on with your life and focus on your positive strengths and learn to manage the negative. http://www.ppc.sas.upenn.edu/
But I'd argue that a psychiatrist is a medical specialist in the same way that a cardiologist or a urologist is. Everyone needs to be aware of their cardiac health and see their General Practitioner if they have concerns. Not everyone needs to be diagnosed with a disease by a cardiologist. Ditto mental health.
