I don't know if I agree with this. You think they are voyeurist because they don't share their own life with you. But that's the way therapy is designed. Once you have a relationship that goes two ways (friendship) there is less room to deal with your own issues. The other gets an equal amount of your energy to talk about their own troubles. But T's don't need to use your energy, that's what you pay them for. To have an 'unequal' relationship in which it's all about you. They get your money instead of your energy. And they use the money to build a life in which they can get their own needs filled with other people. All so they can be there for your needs a 100% when in the therapy room.

This blog from a T is really insightful on a lot of things, I'm linking to the part about money/what's in it for who, but if you feel like it you should read some more on there. (Thanks to Solepa for showing me this blog)
