The conclusion of this essay should be neither surprising nor outrageous. A corporation is a machine specifically designed for the sole purpose of maximizing shareholder value. If that's not what it's doing, it's malfunctioning.
We the people have, via our elected representatives, chosen to have a system where corporations control what healthcare we can receive. If you want to blame someone (which isn't productive) then blame the fellow Americans whose votes have supported and continue to support the current system. They're the ones whose job is to make decisions guided by morality.
Blaming corporations is particularly unproductive because they can't make decisions guided by morality. If they appear to do so, it's because creating that appearance is expected to maximize shareholder value and the appearance will be maintained only as long as it continues to maximize shareholder value.
People laugh at the products with warnings on them against doing something that should obviously be a bad idea. Well this thing says "aim away from face" and the public keeps aiming the thing at its face. Whose fault is that?
