we are a republic, not a democracy, or we were a republic until senators started getting publicly elected by citizens rather than state legislators.
I guess you've never actually looked up the definition of "republic".
a (1) : a government having a chief of state who is not a monarch and who in modern times is usually a president (2) : a political unit (as a nation) having such a form of government
b (1) : a government in which supreme power resides in a body of citizens entitled to vote and is exercised by elected officers and representatives responsible to them and governing according to law (2) : a political unit (as a nation) having such a form of government
This is what the rest of the world refers to as a "democracy". The "direct democracy" that is your boogie man does not exist anywhere in the industrial world, any more than the fictitious "free market" does. Capitalism is an economic system, not a political system. Capitalism operating under the control of a republican (small "s") system is a good thing. A society being ruled by capitalism is not. The "invisible hand" is also blind...and dangerous to those who are not rich.
