While health insurance and health care are not the same thing, it is generally true that those without health insurance do not pay for routine health care and end up as a burden on the (government funded) emergency room system when something serious arises. The future (assuming reading the questions by the Supreme Court justices reflects their final vote) is bleak. What the so-called conservative side seems to want is a complete government take-over of health care. (I use so-called, since the law being debated is originally a conservative proposal created by the Heritage Foundation.)
Why is government take-over the result you may ask?
Without increased participation, the private insurance market will vanish fairly quickly. This will leave 3 groups of people: Those on Medicare (government funded health care), those employed by government (government funded health care) and those dependent on the publicly funded hospitals (again government funded health care). By killing the option of private insurance (which the mandate, in some form, is the only way that will happen) the conservatives on the court and congress ensure we will have only a government funded and controlled health care system. You would think all those Harvard educated lawyers (well some are Yale) on the Supreme Court would see the obvious consequence of their views. But then, they all have government funded health care today so they don’t see any changes.
