Margaret - as others have said housing benefit allows people who would not otherwise be able to put a roof over their heads to live somewhere. I can assure you that many of those receiving such a benefit will be living in properties less than ideal - for all sorts of reasons - because a) there's not exactly a lot of choice at the lower end of the rental market and b) landlords who accept HB are few and far between.
In other words, housing benefit isn't like winning a prize - it can't be seen as a welcome bit of 'extra' money .... it goes, immediately, on rent.
Please don't bemoan the fact you never received HB .... why would you in any case, I think you said before you own your own home. And that, in itself, is something to be grateful for. With your own home - a 3 bed IIRC ? - you have the option of downsizing and releasing equity. Granted, you might not want to leave your home - and I understand that - but nonetheless being a homeowner gives you that potential choice. People who rent obviously don't have the same option - and they can be effectively forced to leave with relatively little notice at any time.
There's absolutely no need to be snipey about those who receive HB given your own relatively fortunate circumstances.
And paying for grandchildren's parties may be all well and good, and kind and generous of you but again you must see you're lucky to be able to do this, if you choose to do so. Presumably the grandchild didn't hold a gun to your head ?
Choosing to spend your money on non essentials like that cannot be used as justification when you seem desperate to 'prove' that, actually (in your opinion) you're not all that well off. Compared to the super rich you're not of course but then that applies to most of us .... compared to a much larger percentage of the population then you are. Can you not be thankful for your security instead of repeatedly producing silly examples in an attempt to paint yourself as living in some sort of genteel 'poverty' ? ...... I cannot stress enough how I (and millions of others) would be over the moon if we could ensure a retirement like yours - especially a 'retirement' where we'd not actually worked in paid employment for decades anyway (instead of one which followed an extended period of paid employment - who knows how much further away the state pension goalposts will move ? - as well as juggling raising our kids at the same time).
