http://www.statistics.gov.uk/CCI/article.asp?ID=1296 shows that for most of the last thirty years, inflation in the UK has hovered between 2 and 5 per cent. Even at the uppermost figure, you wouldn't have expected prices to increase more than 125 per cent between 1983 and 2008, when in fact they've increased 667 per cent. If we could find a published quote referring to price complaints, this would be ironclad, but even if we can't I still feel it's decent content. After all, it's much better supported than most of the stuff in the article and people are only objecting to it because it's criticism.
