Whereas for-profit organizations exist to earn and re-distribute taxable wealth to employees and shareholders, the nonprofit corporation exists solely to provide programs and services that are of self-benefit. Often these programs, services and policies are overlooked and not otherwise executed or enforced by the government. While they are able to earn a surplus, more accurately called a profit, such earnings must be retained by the organization for its self-preservation, expansion and future plans. Earnings may not benefit individuals or stake-holders. While some nonprofit organizations put substantial funds into hiring and rewarding their internal corporate leadership, middle-management personnel and workers, others employ unpaid volunteers and even executives may work for no compensation. However, since the late 1980s there has been a growing consensus that nonprofits can achieve their corporate targets more effectively by using some of the same methods developed in for-profit enterprises. These include effective internal management, ensuring accountability for results, and monitoring the performance of different divisions or projects in order to better benefit from their capital and workers. Those require satisfied management and that, in turn, begins with the organization's mission.
