I completely support universal benefits (and am opposed to cutting child benefit), but think WFA should be means-tested. The reason is that child benefit (or family allowance as it was in one of its previous incarnations) is part of the original conception of universal benefits within the welfare state - the original rationale being that over the lifetime of an individual, in order that all citizens share in the creation of a socially secure society (the cradle to grave principle, where everyone has an investment in sharing social risks), a child is in receipt of a universal benefit (even if a token benefit), people of working age pay in to the system, and then those who are not working or have retired are again recipients of universal benefits. So everyone both takes out and pays in at various points in their lives. Child benefit/family allowance was (and still is) also the way non-working women caring for children accrued their state pension 'stamp' (recognising that raising children was also a form of paying in to society as much as working.) That was the original idea behind the conception of social security as something a whole society shared in rather than just charity handed out only to the poorest or most unfortunate.
Winter fuel allowance however is an extra benefit that I don't think has been around that long - does anyone remember when it was introduced? I don't recall it before the late Major era but maybe someone else knows more about its history and can comment? In any case the case for keeping it non-means tested is far less clear. Child benefit might be paid to the parents, but it is in fact really the child's benefit (and children have no income of their own so can't really be means-tested); whereas WFA could actually be quite easily means tested, as other posters on the thread have suggested, for example by tying it to the pension top-up for poorer pensioners. (Don't even get me started on the bus passes, which cost the taxpayer money in capital grants even if they're not used, and cost even more if they are....) Why can't poorer pensioners just get a slightly bigger top-up to reflect the cost of fuel, instead of handing out cash amounts to all? My dad spends his on cases of wine :( Compare how easily the coalition were able to get rid of the child trust funds and health in pregnancy grants with no public outcry at all. It's purely because the grey vote is a voting bloc (and I hear few complaints from that age group about the axeing of universal benefits for children - the children who will be paying for their pensions, healthcare, etc!)
Also completely agree with the poster who said there's an attitude of pulling up the drawbridge from many older people who benefited massively from a very favourable economic period between the 60s and 2000s and are completely unwilling to acknowledge how different things are for younger generations now. And in the main, most didn't have to work that hard - I have never seen any of my parents or their friends working the routine 70 hours a week both I and my DP work and have done for the last 10-12 years - we're exhausted, often ill, and we still can't afford to buy so much as a one-bed flat. The idea of retiring on a nice pension, or even being able to support a mortgage and family on one salary with one parent at home as our parents' generation did, is just pie in the sky for us. It would be nice if the boomers acknowledged this (instead of whinging about hard done they are because they want to retire at 62 but will have to work until 64 as my parents have taken to doing....) Obviously not all boomers are in nice situations, but statistics overwhelmingly show that that age group owns the vast majority of the UK's wealth and assets and had increased both wealth and income share more than any other group over the long boom. (Whereas from about 1999, unprecedentedly, incomes for people in their 20s and younger started to decline as a share of UK incomes compared to older groups.)
