Part of it is that some doctors are hesitant to prescribe some of the most powerful pain medication, out of fear of patient addiction and potential legal trouble.
Indeed, in my experience many anxious patients who would benefit from benzodiazepine treatment are so worried about addiction and other problems that they deny themselves an important potential pathway to well-being.
America's government-spending addiction and its lackluster system of public education are the two greatest impediments to achieving the country's potential.
