listed law firms, page-30

You are far from ignorant - the legal and medical professions are both governed by ethical principles and regulations. In fact, it could be argued that your (correct) insights extend to other professional services - these other industries may not hold the traditions and history of law or medicine, but client/patient relationships can (and are, on occasion) potentially be exploited on an individual level. Corporates may not be well-received by these otherwise independent professions, but should this in itself preclude listings on public exchanges? Should IPH, PRY and MQG (for example) be delisted because they offer professional services?

RHC is a hospital operator, so the interactions within our healthcare system are too complex to discuss here - but there is adequate opportunity to exploit government, insurers and patients.
