Of course people will die, that's part of life.Even if Labour doubled the WFA and gave it to Joey Davek and Pete pensioners will still die this winter as they have in previous winters . That is the reality. People will seek to exploit those deaths regardless and this shouldn't be used to shape welfare policy. Labour need to focus on doing what is correct - namely means testing the benefits to ensure the welfare budget is spent only on those who really, really need it.
The argument against this is that the quality of life for those people will be adversely impacted by the loss of the WFA at a time when they have to make choices as to how they spend their budget. Some will have little or no understanding of the benefit system (or struggle with access) to apply for other funding and it has the possibility of hastening deaths of people who may chose to forge heating in favour of something else.
The difficult is that the economy is in such a poor position, despite years of previous austerity measures, that some targetted action is needed but unfortunately, because of the austerity measures, there is now no state/public infrastructure for people to fall back on.
Its very hard therefore to believe that anyone previously championing/dismissing austerity or making glib statements about poor budgeting of younger people is sincere in their outrage about this, because either they dismissed the issues previously when it didn't impact them/those they know or they didn't care because it was upsetting those on the opposing political spectrum.
