I don´t think that trying to correct the verticals in this sort of shot is relevant. In fact, I perceive it as totally counterproductive in that it robs the original image of its photoreportage style, which it had captured rather well, in my opinion.
Why mess with the content of the room? People, particularly in what seems to be a fairly poor environment, do not have the choices of space and orderly living. The TV is often left on all day - fills the mental vacuum, perhaps - and I think your shot shows everything in a gritty, realistic way. We are not talking advertising pictures here!
Good shooting - Rob C
