You’ve conveniently, or erroneously, forgotten about the triple lock.
Average earnings are currently growing at a faster rate than inflation, and that situation appears likely to persist over the coming year.
So your pension will increase at a faster pace than your cost of living, and any further decline in inflation relative to wage growth will make you better off. So falling inflation will in fact make you better off in the current situation.
Also, the point isn’t solely about pensioners - across the economy, earnings are currently growing at a faster rate than inflation. When the opposite was the case, and inflation was higher, you were all jumping up and down complaining about the real terms decline in income. When real terms growth is restored, you fail to recognise the change.
Frankly, some of you lefties need to look at the bigger picture and not think only about yourself and your own personal situation.
