> I don't live in the USA, so i'm just repeating whats literally taught in school where i'm from
You spoke so certainly about the subject that that was not apparent. Maybe it should have been a question instead?
> there were no metropolis like we have them today back then
In the US there were, and the early development of the US is the reason for the electoral college. You had sprawling cities like NYC having to vote next to people who took months to get to the East coast for voting. Their problems were very different and the electoral college helped balance the concerns of cities that have easy access to imports and labor with areas that had no such things. On the larger scale it helped protect smaller states and territories from the policy and influence of larger states and territories. Again, their problems are very different, and in current day translate to what we end up referring to as urban, suburban, and rural.
> Nobody said that rural people being represented is an issue, its nonetheless a fact that they're overrepresented,
In the US they're not and you still haven't answered my original question, which is how are they overrepresented. You're just stating that's a fact, but it's really not.
