This idea makes more sense:

The pharmaceutical companies urge you to see your doctor to see if a certain drug is right for you. Scare tactics pure and simple. The drug companies also send salespeople to doctor’s offices, urging doctors to prescribe their products. This is big business. Now, if a doctor prescribes a medication and it has a harmful effect, here come the lawyers urging you to sue the doctor and the drug maker. The doctors need to have ample malpractice insurance to cover any unexpected results from prescribing these drugs. The same for the drug makers. Who gets rich? The lawyers and insurance companies.

Don’t expect the government to do anything about this; a majority of our lawmakers were lawyers before getting into public office.
