Answer:
The founders of the United States were deeply influenced by republicanism, by Locke, and by the optimism of the European Enlightenment. George Washington, John Adams, and Thomas Jefferson all concurred that laws, rather than men, should be the final sanction and that government should be responsible to the governed. But the influence of Locke and the Enlightenment was not entirely happy. Adams, who followed Washington as president, prescribed a constitution with a balance of executive and legislative power checked by an independent judiciary. The federal constitution, moreover, could be amended only by a unanimous vote of the states. Eager to safeguard state liberties and the rights of property, the founding fathers gave the federal government insufficient revenues and coercive powers, as a result of which the constitution was stigmatized as being “no more than a Treaty of Alliance.” Yet the federal union was preserved. The civil power controlled the military, and there was religious toleration and freedom of the press and of economic enterprise. Most significantly, the concept of natural rights had found expression in the Declaration of Independence (1776) and was to influence markedly political and legal developments in the ensuing decades, as well as inspire the French Declaration of the Rights of Man and of the Citizen (1789).
Plantation owners turned to the enslaved Africans as a labor force because they were not paying them for their work, instead they were just providing shelter and food for them. Also, they had total control over them because they owned them, thus were able to make them work as much as they wanted and the slaves couldn't do anything about it.
