When Andrei Schleifer (2004) wondered: "DOES COMPETITION DESTROY ETHICAL BEHAVIOR? ", he also assumed that the performance coming from" the competition that is the fundamental source of technical progress and wealth creation in the world " remain THE factor to be maximize.

therefore the question is, ethics and responsibility must computed as parameters, to be minimized in a model, or a simple cost to pay, especially when companies are performing well, or contrarly it is a time-varying perspective, as Benjamin Friedman (2004) demonstrates, "societies grow richer their views of what is ethical change as well", ethical considerations seem to be promoted for the long run as belonging to private morality.
