Both politicians and big business desire monopoly. Obamacare over time, being one of the largest transfers of power from elected officials to a few select corporate entities, will narrow the field of competition among health care providers to a select and politically connected few.
This is desirable by politicians because as citizens become more beholden to the state for an essential service such as health care, the more people can be controlled. Big business equally desires this outcome because larger organizations tend to be slow to react to market changes, while smaller businesses are far more agile. This small-business advantage is removed when a market is driven by political influence and not the will of consumers. Such influence can only be bought and sold by those entities with vast and expendable resources. This is the real advantage of being a large corporation, therefore such companies use this to their advantage and most politicians are more than willing to oblige.
This is obviously the intent and result of Obamacare. According to Fortune.com, part of the Time Magazine network:
Based on current demographic trends alone, today’s dearth of primary care practitioners is destined to get far worse. As a result, prices are rising, and competition is falling, as big hospital groups rush to hire all the primary care doctors they can find. Once one or two big chains control most of the family doctors and general internists in their markets, rivals can’t find the troops to challenge them. That’s creating oligopolies in markets across the nation.
