The system simply forces the political powers to consider people from a bigger part of the country, which are citizens just as the others that live in more heavily populated areas. This does not mean that the politian can simply ignore people in more populated areas, because he/she still has to please them, otherwise they will not vote for him.
Mob rule (a.k.a. Democracy) is not a good idea. Venezuela is a great example of this. A dictator was literally voted in by the mob, because if people realize that if they band together, they can vote to explore a certain group of people, they will do it.
The U.S. Constitution has the primary goal of limiting government's powers and avoiding mob rule is crucial to this. It simply is a stupid idea that people from a handful of big centers have a disproportionate amount of power over the lives of people living hundreds or even thounsands of miles from these centers.
After all, we're talking about a FEDERAL election. It only makes sense that this election takes in consideration the WHOLE COUNTRY, otherwise there would not be much difference between this election and the ones in local state and municipal elections. There's a reason for this difference to exist.
No. The electoral college is rooted in slavery and house apportionment.
Remember that only white property owner could vote but the electors were based on senate and house representation. Hence why there are 538 electors today.
It was never about the whole country.
