I think it is the aim of the Tories to means test-pensions. This is why they are pushing through legislation to access the bank accounts of pensioners, who are not currently means tested, and why they have introduced voter ID. They will end up based on household income, which is deeply unfair to two-income families who have both contributed tax. Why should someone who has paid tax as an individual have their retirement income determined by other members of their household?
Ultimately they would like all benefits to be means-tested, including bus passes, prescriptions, child benefit (which is already means-tested, and will soon become another 'household income-based' benefit), free GP appointments and A&E visits, and anything else they can find a way to withdraw.
They will, of course, call it 'targeting', and make it increasingly difficult for anyone to claim the things that we used to take for granted. They have sold a lot of young people on the idea that pensioners are grasping and unproductive (just take a look at Mumsnet to see some shocking posts about the older generation), and have a good chance of getting away with cutting pensions if they claim it is to pay for childcare or tax credits.
The only thing we have in our favour is that older people are more likely to vote, so we must all be sure not to fall for the 'they are all the same' line, and to get voter ID if we don't have it already.
