Despite ShootinStudent's basic misunderstanding of why health care costs are increasing, he is correct to an extent that health insurance companies are a causitive factor in those increases. But so is the Medicare program that he is so in love with. As is Medicaid.
There is a very fundamental reason for the excessive yearly inflation in health care costs. ShootinStudent's hatred for insurance companies, and big business in general, has blinded him to that reason.
Health care costs are increasing at such a great rate because Medicare, Medicaid, and the health insurance companies, through their very existence, make available to the health care industry a huge pool of dollars to pay for care. Naturally, health care costs will increase to absorb that pool of dollars. The larger the available pool of dollars, the more costs will increase to absorb that pool.
It is the same in any economic exchange. Costs increase to absorb the available dollars. There is nothing evil going on there. Stupidity maybe, because of people's basic lack of knowledge as to why costs increase, but nothing evil.
