No-one is saying that all pensioners are rolling in it, far from it.
But many, many are very comfortable, so in times when many younger people have seen significant cutbacks in Government help, it is not right that pensioners should continue to be prioritised at the expense of everyone else. Remember that the state pension has continued to be uprated by 2.5% year on year in times when public sector employees and working age benefit recipients have seen years of freezes or 1% increase at best. Employees have seen pay freezes and cuts in take home pay due to increases in pensions contributions.
Mummy It sounds like your DM is a victim of bad luck and poor choices, but I question the accuracy of the £400 pm that you say her income is. She's had equity release, so it sounds like she's already spent some of the money that would have given her a more comfortable retirement.
If she really did work as much as you say, then she would be entitled to the full state pension, which for her age is £130 per week, plus you say she receives company pension that makes her ineligible to pension credit, so that should mean she has an income of close to £600 pm, not £400?
Not riches obviously, but maybe not the picture of sitting in the dark eating cold beans that you paint? Her outgoings for a single pension in a 'tiny tiny bungalow' will be low so its not like the £12 a month for a TV licence is going to mean the choice between heating and eating? There will be many younger people with more people to feed and clothe on similar amounts of money.
