The Hospital Society, where almost everybody is ill, was predicted by the great evolutionary theorist WD Hamilton, as an inevitable consequence of mutation accumulation, mainly (but not wholly) due to the decline in the massively reduced selection-out of deleterious genes from a reduction in child mortality rates from more than 50% to about 1%.
Hamilton predicted that the Hospital Society would at first be the more-impaired being looked-after by the less-impaired; but as things proceeded, firstly the less-impaired would fail to look-after their sicker compatriots, and then the less-impaired be unable to look after themselves...
At which point current civilization would collapse utterly; and some other form of living - presumably much poorer, simpler, smaller scale - would eventually supervene.
The Hospital Society is already here, and the trajectory is as Hamilton described; except that the illnesses are mostly "psychiatric" - that is, they are impairments in fitness; visible in sexual and social pathologies of behaviour.
In other words; the major form of - presumably genetic - illness in the current West (and perhaps elsewhere) is seen in the endemic majority suffering from a wide range of psychological impairments that effect even, or especially, the youngest generations...
With each generation more extremely and pervasively impaired in their biological fitness than the one before.
It is important to clarify that biological fitness is an objective concept; which is a measure of the chance of reproductive success in a given human society.
Reproductive success requires first survival, but then fertility of more than the threshold of replacement fertility (somewhat more than two children per woman, the exact number depending on societal child mortality rates).
Furthermore, the more-than-two offspring must themselves be reproductively viable (i.e. the offspring must want-to, and be-able-to, themselves reproduce above replacement). In practice, this means an average of at least three surviving children per woman.
The problem with mutation accumulation is that it can become terminal, when mutations accumulate faster than natural selection can sieve them out; and this will happen much more rapidly and inevitably when populations are shrinking; since natural selection can then only be very weak and slow.
Looking around at the world, I see that genuine biological fitness has become extremely rare among adolescents and adults; and those who are among the most "health and fitness" focused are among the most psychologically pathological.
We live in a world of sickness; a society where sickness is the norm and viable levels of biological fitness are almost unknown.
My own impression is that the situation has become irrevocable; not least because in a world where everyone is psychiatrically impaired (to a greater or lesser extent) then (almost inevitably) the mainstream societal ideology becomes one in which psychological (sexual and social) pathologies are defended, rationalized - then promoted and supported.
A genuinely spiritual religion - that recognized a world beyond the material and the possibility of eternal life - might be able to provide a world view in which Mankind could honestly face this reality, and learn from it in ways that would be of benefit to our life beyond death...
But there is no such religion at the social level; and therefore the social and individual experience of the Hospital Society is likely to be almost wholly negative: a matter of more and more material suffering and relentless collapsing of physical functionality.
What positive perspective might we adopt as such a scenario unfolds? As long as there is life, there are reasons to live - or else God would not be sustaining us alive.
Rather than focusing primarily or exclusively on present happiness and physical survival, which can - at best - be a merely temporary extension of our finite mortality; we need to understand and learn from what is happening.
And by learning, I means spiritual learning - the learning of fundamental lessons such as those concerning the human condition, divine creation, and God.
