decisions need to be made by the minds with the most salient thoughts on a subject. one vote per person in a "perfect democracy" gives the majority of voting power to city-dwellers who live on margins, with little to no agency in their own lives. by creating the electoral college, a weight is provided away from heavily populated areas and towards the low-population areas that actually support the economy directly - farmers, miners, etc.  it's a lot like the original american constitution insisting that only land owning white men could vote. land-owning ensures that decisions are made with a long time horizon. white limits voting to the race that created this particular civilization. and "male" means crazy goddamn females didn't vote. what a golden age it must have been...
