Eh? While getting hip replacements, for instance, is subject to priority (young person that is a construction worker has a high priority, elderly golf-player has a low priority) it is not like you stop qualifying for it. Sure, it sucks, and some elderly managers/CEOs get private insurance in order to be able to get stuff fixed faster, but it is not like they get told "Sorry, Comrade, but the State has determined that your Social Usability Index is below 0.5 and thus you will not get any care."
We still do eye surgery on old people, even when they are unlikely to reap the benefit for more than one or two years. We don't leave our elderly to rot because they're no longer "useful."
