From Liberating The Supply Side by John Goodman
Ask yourself this question: If Blue Cross were paying all the drug bills, would Rx.com even exist today? Would Wal-Mart be offering $4-a-month prescriptions? Would Publix be giving away antibiotics for free?
The fact that there is the most price competition in the market for drug therapies and the least for hospital therapies is an illustration of Goodman’s Law, which says that innovation and entrepreneurship are inversely proportional to the degree of third-party payment.
