Cost and profit play a central role in health debates (particularly statins).
As diabetics we (probably) realize that looking after ourselves is the most important part of tackling the condition. Yes, we need advice (whether that is good or bad is part of a wider debate of course) but after we're cut loose, at least for a few months before our next check-ups, we need as much help as we can get to tackle things. Self-monitoring surely must be part of that (in many cases) to help understand fluctuations and management of the condition.
Short-termism is art of the problem. £100 spent now cold save the NHS £1000 down the line, but the £100 isn't available, or so we're told. I've seen posts on here where people can't afford meters, frightened people who want to help themselves but are unable to do so. Wrong surely.
