That’s a large part of what it’s for

“Are we to consider men entrusted with power as the receptacles of all the depravity of human nature? By no means. The people do not part with their full proportions of it. Reason and revelation both deceive us, if they are all wise and virtuous. Is not history as full of the vices of the people, as it is of the crimes of the kings? what is the present moral character of the citizens of the United States? I need not discover it. It proves too plainly, that the people are as much disposed to vice as their rulers, and that nothing but a vigorous and efficient government can prevent their degenerating into savages, or devouring each other like beasts of prey.” – Dr. Benjamin Rush, Columbian Herald, April 19, 1788
