My point is that swimming does not contribute to the economic activity of the country (other than employ a few people in the leisure 'industry'). A few deaths here and there are in the most part avoidable, and quite often as the result of misadventure where the casualty could swim but took too great a risk.
Neither does swimming contribute to somebody's ability to fend for themselves rather than be a burden to the State, other than as part of a general fitness regime which can be achieved in other ways - swimming is unique in that it requires facilities that are of no use for anything else (sailing model boats, anyone?).
So where does this imperative that everyone should be taught to swim (like it or not) come from? Obviously it is now propagated by enthusiast groups "I enjoy it therefore so will you (eventually)" - personally I regard the whole process as a tedious waste of time (I have swum a mile, but only as a personal challenge and I would never want to do it again). The origins, I think, must be when it was fashionable to "take the waters" and all that best medical practice could offer as a cure-all was immersion in sea water.
Councils seem to agree. How many public baths have been closed to save cost, even now leisure centres come under fire on a regular basis. In some instances an enthusiast group has formed a trust to take the facilities over, so they get the facility at zero or little capital cost but at least it then has to run on its own income. This seems the right way to go.
