The founding fathers didn't fear true democracy. It simply wasn't practical in 18th century America when information
traveled as a fast as a horse. How we elect a President is a remnant of this.
Go read some history books ... the founding fathers referred to the "common people" as "the mob" and thought of these people as contemptible .
They believed a direct democracy would work only in small city-states as in ancient Greece.
They never considered a direct democracy and the thought of a democratic republic was very revolutionary.
The founding fathers never thought of all the population but rather the ruling class or gentry.
You had to be a man, white (mostly) and a land owner (or pay a poll tax) to even vote for the representatives.
Regardless, a representative group bargains for you.
Too bad Paul Revere did not have a cell phone.
