this is interesting. i always thought it would be more of a circular kind of thing. who do you think is at the top of the pyramid? do they need therapy, or do you think you transcend the need for it by the time you climb the pyramid?
I guess the roles within this world are pyramid shaped, training and supervision are what I see as the more rarified aspects. Which doesn't suggest a hierarchy of those roles going to the best people.
my perspective is at a certain point therapy becomes about growth rather than healing, though it never loses that aspect. Some wounds never totally heal.
Then you gotta find the bartender who tends the bar at where the therapist's bartender drinks. It'll be a dive, and all the advice anyone gets is "beer or shot?" And the dive's bartender doesn't need therapy because they've already accepted that they are past saving.
