you see the problem is - that your're assuming that it's only those on benefits who are living in poverty (and forgetting that many who recieve benefits are actually working), there are plenty of working families who live in poverty - often because they don't tick the right boxes (or are too ashamed/proud to claim).
I too have seen absolute poverty some of my exIL's live in it. It is shocking, but it doesn't make the relative poverty of the UK any less worse. Likewise my exIL's living in relative poverty in their own countries (far below the standards we would consider "acceptable" here) don't think they live in poverty, as there are others worse off than themselves in the same country.
Poverty is a very wide ranging term, and isn't just about money and material goods, it's about opportunity too, health, educatin and so much more.
My oldest exSIL (now living in the UK) has retrained since she came to the UK - to become a Family Support Worker - working with families in poverty - so obviously it's not quite so cut and dried.
I generally do ok on benefits, I get by, and because I budget extremely strictly (and exH took the debt with him so I came ont them with a totally clean shhet - a very very fortunate position indeed). However this morning I had a major panic on, my washing machine stopped working, There is no laundrette nearby (there is one the other side of town I believe) and it's expensive anyhow, and I have no means of getting there other than taxi. I couldn't afford a call out. Thankfully I have a good educatin behind me, and grew up in a family where aspiriation was encouraged, plus of course I've got internet access - so I was able to get online and find the information I needed to fix it myself.
The alternatives - laundrette and call out were out of the question - just not enough money to do that. If it had been a serious prblem that I couldn't fix (or couldn't be fixed!) I'd have been well and truly screwed.
The thing with those on low wages, and benefits who aren't so fortunate as I is that thse sorts of situations will arise regularly, the children's shoes will need replacing, the oven breaks, the light bulbs blow. They can't afford to put the heating on in their inadequate housing, mould grows, and health care issues arise,
Just because absolute poverty in the 3rd world is worse in terms of basic needs doesn't mean there aren't some similarities.
Too many people think that
Poverty=benefit
Poverty=purely a lack of cash.
If it were really that simple we should just be able to thrw cash at all the poverty stricken areas of the world and all would be hunky dory............
