Bribing Members of Congress is a cost of doing business for Big Pharma. Lobbying and bribing congressman (which in reality is just giving them their cut of the profits of what they rip off from American consumers) is nothing compared to what they spend on advertising. As for who to bribe... they have it down pat. Here are the Big Seven for the 2012 electoral cycle:

Cantor, Boehner and McCarthy control the House agenda, so they automatically get their cuts. Fred Upton is the Chairman of the Energy and Commerce Committee and Pitts chairs that Committee's subcommittee on Health and Eshoo is one of the senior Democrats on the Committee. And Dave Camp is the chairman of the Ways and Means Committee and chairs the Joint Committee on Taxation. For a few paltry bucks to a handful of greedy corrupt Members of Congress, Big Pharma gets to charge American consumers 400% more than people anywhere else for the same drugs. What could be better?

Dr. Syed Taj is the Democrat running for the now empty Thaddeus McCotter seat in the Detroit suburbs. He thinks John Aravosis hit the nail right on the head...

"Much more than just dollars and cents are at stake in the health care and pharmaceutical industries. When insurance companies raise rates or deny coverage to increase profits, or when pharmaceutical companies increase costs because the demand will be met regardless, the wellbeing and general health of millions of people are affected. When middle-class Americans are forced to pay upwards of $8,000 a month for cancer treatment medication, it’s obvious our priorities are not in the right place.

It’s been shown that drug companies price discriminate-– they sell drugs in Canada and elsewhere for less because they know they can still hike prices in the United States. This is proof that a laissez faire pharmaceutical market does not work; the
greater the profits for drug companies, the sicker and poorer people become."
