Should ALL Therapists be Trained as Specialists?

Chris spitballs about the ongoing problem, albeit now much smaller problem comparative to 10 years ago: that many patients consume services from the local counseling center, just to linger in treatment for 12 to 24 months and make minimal progress. That's disempowering and discouraging to patients - not to mention expensive. Should the graduate training process include enterence into a subspecialty? In other words, should therapists, like physicians, be trained and licensed not merely at mental health professionals, but more specifically as a particular sort of specialist within the broader field?
