I’m not necessarily on board with every point this video makes but the fundamental truth is in there: health insurance companies face pressure to increase profits, like any other business. But they are such huge businesses now that they end up spending tons of money lobbying, way too much of what each member pays in premiums goes to marketing and non-health related costs. They also feel pressure to cut costs and do so almost ruthlessly by denying legitimate health care needs of its members.
We shouldn’t be too surprised as this is the way of for-profit businesses, which health care companies didn’t used to be in the US, they were non-profit entities originally. Perhaps that’s the only way to rein in this out of control system that’s no longer based on providing the best possible care.
