You do realize democracy is a less-than-four-hundreds year old concept?
--Wait, WAT? In general, you confuse citizenship with democracy; and more particularly, you confuse a republic, with a democracy (the USA is the former, not the latter). Democracy is an ancient concept. Equally as old and well known are its many "problems", of which the ancients were well versed. The notion of a republic is an (historically) more sophisticated take on a democracy, and is well over two millenia old (Rome, etc).
