Ugh...he loses me at his first point:
"Long-term psychotherapy can encourage narcissism." And that entire paragraph is ridiculous. Boring I know I am NOT.
My T said we ALL have a certain degree of narcissism...the need to look after and take care of our own best interests. (He was not saying this as a negative, but applying the definition of narcissism, not Narcissistic Personality Disorder.)

From Wikipedia:
"Healthy narcissism
Main article: Healthy narcissism
Healthy narcissism is a structural truthfulness of the self, achievement of self and object constancy, synchronization between the self and the superego and a balance between libidinal and aggressive drives (the ability to receive gratification from others and the drive for impulse expression). Healthy narcissism forms a constant, realistic self-interest and mature goals and principles and an ability to form deep object relations.[9] A feature related to healthy narcissism is the feeling of greatness. This is the antithesis of insecurity or inadequacy."

And it's also normal to be upset when your T goes on vacation! Part of your support system, or your entire support system in some cases, is missing. I don't think being "dependent" on a T is a bad thing.
And I would tell tell the jerk from his example to go **** himself.
I apparently I just need a tough love lecture and a good self help book.
I agree with you...he appears to be biased, and I would say that a lot of Ts would disagree with his argument.
