I think the young generally see old age as something that is so far away it is not worth factoring in to their everyday living. I was lucky in having worked for a national company with an excellent pension scheme which was mandatory so there was no option to not join it. What concerns me more is the view that the state will provide for their needs when the time comes (either via the state pension or by way of benefits). This is a view which is unsustainable given the ageing population of the UK.
While I am not a great believer in means testing, I do think that failure to secure ones own future (where the opportunity to do so was available) should be taken into consideration before extra benefits are awarded.
