I've never really differentiated between 'poor' and 'working' class, so I don't know. I certainly wouldn't class myself as middle class given my family history (we lived on state benefits for a good few years when I was between the ages of 7 and 11). We live in a rented house owned by a housing association, though for all extents and purposes it's essentially a council house. My father is currently a bus driver and my mother works part time as a cleaner in an NHS hospital. Upper poor class, perhaps? I don't know.
