> Labor unions seem like the wrong model for organizing people in a lot of "knowledge workers." A professional association like the American Medical Association might be a better way to structure things.

Please explain—knowledge workers are still workers and the same benefits that labor unions provide to other workers apply just as much here.

Secondly, why would I ever care about a professional organization if I can't use it to collectively bargain? It doesn't seem to work this way for doctors; why would it work this way for us?
