Within a context of mutual respect, this is moral conduct. When employers subject their employees to unsafe working conditions, excessive hours, or poor wages, however, the relationship becomes exploitative and immoral, which can also occur when employees do not perform their duties, steal from their employers, or abuse the workplace. Similar considerations apply to doctors and patients, students and faculty, or ministers and congregations, which may explain our dismay at their betrayal. There appear to be no inherent reasons why prostitution should not qualify as moral so long as hookers and their tricks treat one another with respect. Hookers are immoral when they do not provide the services agreed upon, steal their trick's money, or subject them to venereal disease, while johns are immoral if they do not pay for services rendered, engage in physical abuse, or infect them with disease.
Respect works both ways round.
Even when prostitution happens to be legal, of course, immorality can enter by means of other relationships. When husbands or wives commit adultery and thereby betray their commitments to each other, they are not displaying respect for their spouces and are acting immorally. But that remains the case apart from any fiscal aspects. The difficulties that arise in relation to prostitution are generated largely by its illegality, not its immorality. In those locales where prostitution is legal, such as the sites of Jesse Ventura's youthful indiscretions, women can freely choose this line of work without the intervention of pimps, who turn them into sexual slaves.
