Our Founding Fathers were afraid of democracy, that is why only House members were elected by the people. Senators were appointed by state legislatures and the president is still elected by the Elctoral College.

Democracy is only possible if you have an intelligent electorate. But as H. L. Mencken famously said: "You'll never go broke unerestimating the intelligence of the general public. Mencken also said: "Democracy is the theory that the common people know what they want and deserve to get it good and hard."
