Nope, wrong in many ways.
Foxes in the countryside are doing better than they ever have. Changes to farming practices, and countryside and wildlife management are all benefitting foxes, often to the detriment of many other less prominent species - coz foxes kill and (sometimes) eat them, and in particular they hunt the young of their prey because they are easier to catch. A fox will normally wipe out an entire family of young in one go. Beautiful on the outside, indiscriminate killers on the inside.
The urban environment also suits foxes and their presence there has nothing to do with pressure from rural areas and everything to do with the adaptability of foxes to learn to scavenge as well as filling a void where there was not enough predators.
The overall fox population in rural and urban areas is out of balance as they are better and quicker at adapting to changes in the environment brought about by mankind. They are rightly persecuted, ok lets not beat about the bush, shot, to try and correct that balance. It is mankind's moral duty to do so from the day we started modifying the environment for our purposes. Failure to do so condemns thousands of other animals and even whole species to Extinction.
Crows, magpies, rats, grey squirrels seagulls, are examples of other creatures who are adaptable like foxes.
Sadly there are thousands of species who are less adaptable or slower to adapt that are slowly being wiped out through persecution by the more adaptable animals, sometimes persecution by humans and most worrying by loss of habitat. These are the creatures we should reserve our sympathies for and be directing our efforts at.
