What is your honest opinion on psychologists and psychology firms who sell there internships?

I think its not ethical at all to do that. Its basically robbing people because of lack of knowledge in the field and desperation to make something out of yourself in this competitive environment we all are stuck at, feeling we are not doing enough with what we have. Please let me know your opinion, specially if you are a psychologist who knows people or is one who thinks its fine to sell your internships.
