Nobody knows what the legislation is going to look like, so nobody knows for sure the impact. I worked at a hospital that was in a poor part of town. I can tell you there was a significant population that used the ER as their primary care and never paid the bills. It's not that they get free health care, the hospitals go after them for payment and the number one reason for bankruptcy in America is health related bills. I am now in pharmacy school. The issue I can't get around, and I think is one of the fundamental questions we have to ask ourselves is: How is a private corporation that is publicly traded go to solve the problem?
They have a fiduciary responsibility to their shareholders to return a profit.
They can only make a profit BY CHARGING PREMIUMS AND PAYING FOR AS LITTLE HEALTH CARE AS POSSIBLE. That is a fact. That is what some call a free market solution. I would argue that private insurance is causing much of the problem which is that costs are rising at unsustainable rates. The piece rising the most is ADMINISTRATIVE COSTS. Look it up NEJM has free text studies. Administrative costs in hospitals and insurance companies. Our costs are rising faster than any other country. Medicare has far lower Adm. costs than private insurance.
