Public services are socialised. This means that every single person is not expected to pay as much in tax as necessary to pay for all the services they use. The aim is only that this be the case on average.

So in general people who live is more isolated houses end up being effectively subsidised by everyone else.

In your example the 'problem' stems from a tax base that is too narrow because of administrative and political choices.

In any case, that is NOT the point of my previous comments.
