The main purpose of setting up public corporations is to provide essential services to the people at minimal cost. Public corporations are established by the government to provide services that are necessary for the welfare of the citizens, such as transportation, healthcare, energy, water, and education. Unlike private corporations that aim to make a profit, public corporations prioritize the provision of quality services at an affordable cost. The government owns and operates these corporations, and their primary objective is to benefit the general public. By providing essential services at minimal cost, public corporations help to improve the living standards of citizens and enhance economic development.
