What’s wrong with therapy?

I’m preparing a workshop for a group of psychotherapy students on ‘contemporary issues in psychotherapy’ and am interested in unravelling assumptions (well some assumptions) about therapy being useful and a good idea so if anyone would care to contribute some thoughts I’d be really interested…I’m particularly interested in the cultural and political aspects…I won’t say any more for now – comments and email would be welcome. I’m hoping Johnnie, Mark, Mike and a few others might chip in?
