I would not mind if he raised his rates. I've raised my own rates, although I'm usually hired by the gubment, not individuals. As someone who works for myself, I see rate increases as necessary because it never gets cheaper to be in business for yourself. It's unclear whether the new US tax scheme will decrease or increase self employment taxes. I also see raises as signaling my increased experience/skill/whatever, and they are the only way I can get a raise.

The rates for sessions over the near decade I've been seeing T have stayed the same. My copayment for my insurance went down a few years ago, because the collective T organizations lobbied my provider, the largest in the state, to consider T's as "generalists" rather than "specialists." I.e. the copay to see my family med doc is $20, but it's either $25 or $30 to see a specialist like an OB or a cardiologist. The T lobbying efforts, which did not result in any increases in session fees (those are also negotiated by my insurance), did result in my paying $5 less per session, or about $20/month or over $200 per year. It was a good example of general T advocacy for clients.
