Indeed, the underclass will, in general, not be anywhere near as poor as honest people at the bottom end of the benefits system.
Distinctions must be made.
The underclass works against society; parasites professionally and is enmeshed in petty - and not so petty - crime. This group must be targeted. We are in a war which threatens our entire social base.
Nobody can be a pacifist in this conflict. Society must return to the excellent victorian concept of the 'deserving' and the 'undeserving' poor.
I wish to see society help the former.
