And here’s Alexander Hamilton, from the opening paragraph of the very first Federalist paper, on why that is:
After an unequivocal experience of the inefficacy of the subsisting Federal Government, you are called upon to deliberate on a new Constitution for the United States of America. The subject speaks its own importance; comprehending in its consequences, nothing less than the existence of the UNION, the safety and welfare of the parts of which it is composed, the fate of an empire, in many respects, the most interesting the world. It has been frequently remarked, that it seems to have been reserved to the people of this country the important question, whether societies of men are really capable or not, of establishing good government from reflection and choice, or whether they are forever destined to depend, for their political constitutions, on accident and force. If there be any truth in the remark, the crisis, at which we are arrived, may with propriety be regarded as the era in which[9]that decision is to be made; and a wrong election of the part we shall act, may, in this view, deserve to be considered as the general misfortune of mankind."
