The dirty secret about prescription drugs is that they are cheap. Wal-Mart has done a great public service by making a large number of generic drugs available at $4 per prescription. Not only does this save customers money, it also tells us how much it actually costs to manufacture and distribute drugs. After all, Wal-Mart is a business, not a charity. If it sell drugs at $4 a prescription, it must think that it can make a profit at this price.
The only difference between the generic drugs that Wal-Mart sells for $4 and the brand drugs that can cost hundreds of dollars for a prescription is that the expensive brand drugs are protected by patents. Otherwise, they could also be profitably sold for $4 per prescription.
Drug companies are getting away with everything including the kitchen sink. About time to look into them?
