The next two courses we'll focus on health care. This course number two we'll focus on the issues and structures of health care in America. Course number three, we'll review the Affordable Health Care Act, Medicare and Medicaid and try and lay out the structure of how each of those three programs work. So, I want to start by talking about health care in America and say that it is vast. It is almost 18 percent of the US economy at the moment. It's on track to become 25 or 26 percent of the US economy as the population ages and as we improve our health care technologies so that, generations back, there were many fewer choices about health care. In our time, using all kinds of technologies from medication to surgeries, to implants, to tools, to rehabilitation activities, to top treatment, and increasingly to genetic and genetically focused treatment. We're transforming the way we handle our life and the managing of our bodies, and our psyches over the courses of our lives. So, health care continues to expand. I want to start this healthcare conversation by saying that nobody, I mean nobody in the United States understands healthcare. The system is just too large. People understand a particular piece of it in some detail, they may understand a disease, they may understand a particular intervention, they may understand a particular funding mechanism, but nobody spreads all the way from advanced psychiatric care, to the building of hospitals, to the locating of elder care, to interventions for kids with autism, the realm is just too big. So, my goal in this two courses are not to have you in a place where you have a mystery, but to create a basic kind of structure of how we end up where we are in the US health care debate, and what are our presence structures of health care. One of the people I teach with, Dr. Allen who will encourage you to watch her Ted Tac talk, says that we already have a single-payer system in America because we have the veterans system, we have the public employees system, we have the Medicare system, we have the Medicaid system, we have the Affordable Care Act system, and we have the subsidized system of private health care insurance. So, government is involved in healthcare at every single level of the paying of it, the regulating of it, the training of it, the management of it, the licensing of it. So, we're going to be exploring some pieces to begin to look at the healthcare situation in the United States.
