The literal implements meant to aid in your healing were morphed into weapons of war, crutches into assault rifles, syringes into bullets, and medical tape into an ammo belt. The US health care system is an aggressive machine whose end goal is not healing. This is not to say it is totally unconcerned with healing, but healing is more of a means to an end than an end itself. Investors don't invest in hospitals to help people; their goal is money. Insurance is the part of our health care system that is the most profit driven. The cost of care is so exorbitant in the United States that we are beholden to health insurance companies to have access to routine care.
Having insurance companies as publicly traded businesses is a conflict of interest. In our current system, companies tend to consolidate, decreasing competition. With stock market based profits, a publicly traded company must continue to make larger and larger profits. In the end, they are in a position where they either have to pay their customers or their share holders, and that is a conflict of interest.
