Companies are neither as perfect nor as organized as some describe them, nor as bad as others describe them. They are simply the economic units of our society that are necessary to provide the goods and services we need. We don't want to go back to walking down the road hoping that someone had cheap products in their cart, do we? No better way has yet been found to achieve this goal. Although companies would obviously prefer to market safe products over unsafe products, they feel justified in questioning why they should voluntarily increase the safety of a product if the result is that sales suffer. The provision of seat belts in automobiles is a good example. The leveling effect of government action is essential to improve product safety and reduce pollution. There is no point in urging engineers to insist that their ideas on safety or pollution be adopted if doing so risks jeopardizing their employer's well-being. If such actions harm their employers, have they properly fulfilled the ethical obligations they agreed to when they accepted employment? In exchange for a salary, there is an implicit obligation that the employee will contribute to satisfying the employer's requirements.
