Warren must be mistaken.
Obamacare fixed all these problems. No one can be denied care. Insurance company's profits are capped at 15%, excess profits have to be returned in lower premiums. A minimum of 85% has to go to medical losses. Insurers are free to spend more than 85% on medical treatments, but they can't spend less. They have no incentive to deny treatments, because their profits are guaranteed.
If you are in the middle class, the gov't assigned 20% of your income to the insurance companies, and subsidized everyone making less than 400% of the poverty level. That was the deal. They even took over student loans to make sure there was enough money. It was not possible to make incremental reforms to the industry, only comprehensive reform could solve the problems, so that's what the dems did.
Someone should explain to Warren that they solved all these problems about denying care, and greedy insurance companies ten years ago. They all cheered themselves for it, how come she doesn't know that?
