As to bad schools, the education statistics say the opposite. But if facts are hard for you then I can understand why you'd have a hard time with that.
As to rednecks, that depends entirely on where you've set down roots. There are different places with very different sorts of people. Its not like the area outside the cities is homogenious. Some of those areas will have rednecks. And lots of others will not.
A lot of them are just a little old fashioned. Think of your grand parents. But then you have some that are as up to date as anyone. You wouldn't know the difference at all in some places.
As to social isolation, you're less isolated because potentially everyone you meet will be someone you know. Where as in the city you know practically no one. They're not part of your social circle. So pretending they are is silly. How many people in a city do you actually know? Less then a thousand probably. Okay... so why do you need the other 10 million people? Any of them could die and you wouldn't even know or really care.
As to physical isolation, depends, you can live in the town at which point you will see people all the time. You can walk to the coffee shop, order food at the restaurant, etc. You have fewer choices but at the same time you will know these people so if you want something else just tell them. They'll figure out what that costs in time and ingredients and probably give you a good deal on it. They might even name a menu item after you because why not. Try to get that in a big city.
As to not wanting to drive, you can avoid driving in a small town if you want. Just live in the small town itself and its no big deal. You'll walk less there then in most big cities and you won't even need to deal with mass transit. A town of 70 thousand can be walked from one end to the other in about 5 to 10 minutes depending on how much of a hurry you're in.
As to poor services, again it depends on what you mean by that? Generally anything a city provides you can be found in small towns without any trouble at all. What do you mean by this?
As to few jobs, that is a valid point however, I think with the internet there is no reason why we shouldn't be able to telecommute to any job anywhere in the world that simply requires us to do mental labor. If you need my physical hands to do something then sure I can't telecommute. But I doubt those are the jobs you're saying you can't get unless you live in the city.
lets say you want to be an investment banker or a programmer or any of the more typical jobs you'll find in a city. Why can't you do that anywhere on earth with decent internet?
As to going out your door and doing something, you're going to have to define that. They have that in small towns as well so I don't think you're aware of the options. Many small towns make a great effort to provide social activities, concerts, some have full opera companies, plays, etc. So I don't know what you're talking about here. Night clubs? They have night clubs in small towns as well... you just won't see too many new people in them.
As to it being different in different places. I've lived in a lot of places. You just have know what to look for... you can find a place for everyone.
What I find galling is that the cities exert political control over the countryside while at the same time only being able to do that because of the subsidies that allow for that population density.
Make areas more autonomous or cut the subsidies off and I'm happy.
