People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf.
They were both MDs in China, but can't afford to or don't choose to be re-certified to practice as MDs here.
They told me that they left China, at least in part, because the pollution was too bad, and they didn't think it was healthy to raise their son (who has serious asthma) there.
I don't blame them for going the TCM. In the U.S., most states don't regulate TCM so they can setup shop and start giving treatments without resistance. Compare that to having to spend potentially tens of thousands of dollars in re-cert examinations and even mandatory education upgrades, just to have the chance to maybe get hired by a hospital.
I wish the U.S. had more licensing for TCM though. There are lots of effective practitioners out there but without licensing you could just as easily end up seeing a hack and that creates a bad reputation for the field.
