So? That doesn't mean they should be in charge.
Don't drive it to a false extreme. They are not "in charge". There are a couple of places where we ensure their issues carry sufficient weight.
One person, one vote.
Is not actually a foundation principle in the construction of our representation.
City life (note: not suburban life) is generally a lot more eco-friendly than rural life.
"Ecology" isn't actually the main question at hand, but, if you want to go there....
For example, dense populations support public transport as well as getting to work by foot or by bike.
That is in theory. In practice, it doesn't happen. Cities are where folks sit wasting gas idling in traffic jams, and have entire high-rise buildings heated during times when nobody's even working in them.
So pretending that rural people are somehow more suited to being in charge is highly suspect.
Again, they are not "in charge". That's strawman you should toss out.
But, if you want to continue - the city folk haven't gotten their crap together to take advantage of their potential ecological strengths. If they can't manage that in their own houses, why should they be in charge of everyone else's?
