There can be a 'high cost' to living out in the country too.
The 'direct' cost - lower property taxes, for example - is offset by often having to drive further for basic stuff that you may be able to walk to or use public transport for in a larger city.
There's also a social cost - fewer human interactions - which, for some people, is actually a positive, but it's not for everyone.
Also, opportunity cost can be higher out in the country. You may simply miss out on experiencing things that you would in a city. But in a city, you might miss out on cleaner air, nicer sunsets, etc.
