Rural areas typically don't modify the local drainage (you're not likely connected to a sewer, you have a septic system). They don't become heat islands are there's relatively little pave or concreted. The noxious gasses aren't usually a problem due to lower traffic, usage and density, except in some mountain valleys where you get temperature inversions over winter that trap some of that.
The problems are technological/economical. Getting power is a pain in the ass, yet we've mostly solved that, likewise with traditional phone land-lines. Internet access is abysmal. I get better internet connectivity on my cell phone than my parents can get in their house because local providers won't run cable/fiber because it's too expensive for too few subscribers, but the federal government mandated access to both power & phone and we have those.
I think you've bought a bill of goods that a certain group of people are selling, without actually having lived it.
I think this is an almost uniquely American phenomenon. In most places in the world, the suburbs are where you grudgingly live when you can't afford housing in the city.
Anyway I was just offering a basic justification for why society would focus on improving lives in cities as opposed to rural areas.
You're assuming a centralized distribution model and that the overhead of centralization is more than made up for with economics of scale.
edit: is that not the implied assumption?
Sure, I suppose it is.. do you mean to suggest that the assumption is false?
Those who are born and raised in rural areas can't just uproot their lives the moment they turn 18 and start to afford, or even enjoy city life.
Because the commute is closer? It's still at least as slow in many places, because of traffic problems generated by tighter clusters of people.
The idea that cities are the most optimal is an idea, not a proven fact. Your experience may support the idea, but mine certainly does not.
The point here is that there are more people living in cities than in rural areas, simply because that has been true for a few generations, and people don't tend to change lifestyles.
People who grow up with one lifestyle realize the advantages it provides, and grow up with a bias toward that lifestyle. That bias coupled with the population difference is the real reason the majority of people don't care about rural areas. Personally, I think we should fight that bias.
