What went wrong with Obamacare?

What went wrong? The rate of increase in health care costs was decreasing under Bush. Now it's increasing again.

"Health care is unaffordable for most Americans. To have any hope of affording even minor medical procedures, Americans rely on health insurance or public coverage to pay much of the cost. About 88 percent of medical bills are paid for by an entity other than the patient. As a result, health insurance has also become unaffordable. The average employer plan costs American families $17,545 per year. A Bronze plan from the exchange for the average middle-age family costs $12,000 per year with combined annual deductibles of $8,000 to $13,000. Provider networks are so narrow that any major procedure is surely to result in out-of-network charges that can be astronomical."
