 The following appeared in an article in the health section of a newspaper.
“There is a common misconception that university hospitals are better than community or

private hospitals. 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 patients. From this it seems clear that

the quality of care at university hospitals is lower than that at other kinds of hospitals.

Businesses and other organizations have overemphasized the importance of working as a team.

Clearly, in any human group, it is the strong individual, the person with the most

commitment and energy, who gets things done.”
