I don't think therapists actually do anything - but I believe most charge what the market will bear. If someone is willing to pay a fee to them, I see no reason for them not to charge it. Usually people have some choice in which one to hire and if one cannot afford a certain therapist, then it is often possible to find one who charges less or is at a clinic or something like that. I don't see it as being because they have been trained or anything. I don't see their education as being all that long or rigorous. People are willing to pay what they charge so they get away with charging it.

And when insurance is figured in - there is a whole other set of shenanigans going on both in the initial charge and the reimbursement - so it may say $100- but $100 is not really what is being exchanged.
