Those regulation changes can mean a successful doctor is suddenly broke. I watched it happen to one. He ran a practice in Yakima and spoke Spanish. He made a killing with medical coupons, and then the regulations changed and he was gone.

From a tech business point of view, the entire medical industry is ripe for disruption, but they keep making regulations to keep the big names in power. I'm expecting WiFi and low level xRay tech to get hobbyists for medical scans and watch it all fall down.
