It is certainly fair or just that a person receive remuneration or compensation for the services he renders to others, although is it is also necessary to recognize that many services are, and indeed should be, rendered freely, as happens within a family, or in a church or in not-for-profit service organizations. Generally speaking, a person is remunerated for his professional work, and, in a normal market economy, with this money the person is able to pay for the services of all the other various professionals on whose work he depends. Hence it is entirely legitimate to seek to be remunerated for one’s work. Moreover, this desire is not, or at least need not be, selfish or egocentric; a person can desire this money to take care of his family or to donate it to a church or any number of charitable, not-for-profit enterprises. Hence a professional will normally seek remuneration commensurate with the (real) services he renders.
This motivation too, however, can be corrupted. It can often lead to greed, the excessive desire for money and material wealth generally. As happens with vanity, greed can lead to a professional providing services that are not what the client really needs or, perhaps more often, cutting corners and not providing the full service for which he is billing the client. So for example, a doctor might prescribe unnecessary procedures that will generate profit for his practice, while a builder may, without informing the client, substitute cheaper materials for those specified in the contract. Greed also leads professionals to engage in many unethical and illegal activities, that are often harmful to the client, to ones’ own firm or corporation and, at times, harmful to the larger society. An excessive desire for wealth can also lead a person to enter upon a profession for which he is not well suited instead of one in which he could provide a good service to his clients with personal satisfaction.
