Honest Abe Said It.

"Kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object. This, our [1787] Convention understood to be the most oppressive of all Kingly oppressions; and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us."
