It can be argued that Demotivation is the primary pathology of modernity. The reason is obvious - modern society has severely-weakened or abolished at least three of the primary motivations of Mankind:
Such that many, probably most, of those engaged in modern public discourse are operating in a context where biological survival is taken for granted, family is actively-rejected, and serious religion is regarded as nonsense (evil nonsense when practised by native anti-Leftists, quaint nonsense when practised by 'minorities').
Over the past couple of hundred years, people often thought and wrote that these motivators could (and should) be dispensed with, and that they could (and should) be replaced by other and supposedly-better motivations - (e.g. spirituality, fluid friendship, Leftist politics).
However, fifty years of experience shows that the replacements are just too feak and weeble to do the job, and the outcome is a massive motivation deficit.
So, modern Man is reduced to trying to get-by on a very enfeebled and impoverished set of motivations - e.g. seeking comfort, stimulation, sex, status; avoiding suffering, pain, social-rejection...
But The Big Three motivations are either absent or weakened to the point of ineffectuality.
Small wonder that modern Man is alienated, nihilistic; lacks courage and honesty; and has become self-hating and strategically-suicidal.
There are plenty of Good Ideas, or at least sensible and practical ideas, floating-around in the mass media - especially old books; but no motivation actually to do them - therefore they are not done, and they will not be done; unless or until Men are again sufficiently motivated.
And Men will not be significantly remotivated until at least some of that triad of Survival, Family and Religion are restored and strengthened.
And this restoration and strengthening will happen sooner or later, because there is no remedy for demotivation and no way of compensating for demotivation - it is a single and sufficient cause of extinction.
So, selection mechanisms will ensure that the demotivated will be replaced by the motivated (specifically, the motivated who can transmit their motivation to the next generation).
A demotivated society will - inevitably, from internal causes - waste all its inherited advantages - dissipate all its strengths, attack all its virtues, fail to defend and renew itself - no matter how great are those advantages.
The motivated shall inherit the earth. But, what kind of earth they inherit will depend on the nature of their motivations.
