the problem is, as i suspect you well know but just like an argument, that many of us have either been in this situation or know someone in the same boat. We don't consider statistics, only the evidence of our eyes and ears which is difficult to quantify in the argument you have tried to forge. The real question is, is it right that working families have to subsist on this level pretty much forever?
I have several work colleagues and other people close to me who have what are considered good jobs, but because of the difficulty of getting started on a mortgage are fuly extended on that front. in previous decades, you could do that, reasonably safe in the knowledge that the mortgage would become a shrinking proportion of your outgoings and that the cycles of inflation, interest rates, fuel and energy prices, etc would be the swings and roundabouts of many preceding years. That just doesnt happen any more. For those starting out, you have a an existence rather than a life to lead. And for a large number, it just doesn't get any better, unless some spectacular life event occurs that raises you up. People have been brought up to believe that if you work hard, behave well and don't give in then it all gets better. the proportion of the population that can enjoy that is diminishing. The cream is all being hoovered up and Thatcher's (and others) desired underclass-those who exist only to consume and survive in order to benefit the more privileged- is coming to fruition.
You can budget your way along, but life becomes a grind. Some respite is needed. If you work, then you deserve the odd spoonful of cream but the sharp elbowed middle and upper classes are having none of that. Every advantage in life seems to be sliding inexorably toward their demographic.
To narrowly focus solely on the cost of food in the context of food bank use is just an argumentative trick that, frankly, shows you and bellside up for what you are, attention seekers who feel smug when they push other peoples buttons and who trot out information that suits their agenda, even though they know that it paints only a part of the picture.
There now, you have been indulged. Respond if you want, I won't be reading anymore argumentative pish from either of you.
