痛苦的分数，580 [转帖我看机警]

"If the primary and concern of a corporation is to make money, then conflict is inevitable when the corporation must also acknowledge a duty to serve society."

"There is a common misconception that university hospitals are better than community or private hospital. This notion is unfounded, however: the university hospitals in our region employ 15 percent fewer doctors, have a 20 percent lower success rate in treating patients, make far less overall profit, and pay their medical staff considerably less than do private hospitals. Furthermore, many doctors at university hospitals typically divide their time among teaching, conducting research, and treating partients. From this it seems clear that the quality of care at university hospitals is lower than that at other kinds of hospitals."
