This situation is so prevalent in society that it has formed society's control structure and that structure has been given a name: the oligarchy. It is described nearly precisely in Plato's republic and it is the basis for control in our civilization--police enforcement, corporate management, judicial officials, politicians--and especially medicine: doctors and the medical and hospital industries that now absorb approximately half our money.
We termed the neurological defect "emotional communication dysfunction." People with the dysfunction cannot collaborate in the normal way because they cannot connect using the emotional communication paths that humans and many higher mammals have. Because of this, they cannot directly sense the pain they inflict on others, and further, they cannot conceive of the long-term effects of their actions. This is a handicap in normal society, but society has been changed by them, as they can be intelligent, and they can cooperate to solve their problems, allowing them to obtain what they cannot create by trickery and force. With time their cooperation became organization allowing groups of these dysfunctional people to gain control over large components of society.
For the West, the development of societal templates such as Plato's Republic, was a locus for their control, as Plato and his followers are credited for the basis of Western Civilization. At the highest levels, Plato's elite, the dysfunction is complete; there is no human empathy, and the system is operated purely mechanically with only affectations to normal humanity allowed to create a thin, yet effective, pretense to humanity. This is medically described as Aspergers In the middle layers of the template is the guardian class; dysfunctional people whose inhumanity is part-time; they have hybridized diseases: bi-polar. Some of the time they are humane and can connect with the mass of normal people, and sometimes they cannot and their disassociation allows them to be inhumane. Without expert knowledge of these dysfunctions, a normal average person is easily confused by the changes, and hence the value of the part-time inhumane to the oligarchic structure.
ADD also appears to be an oligarchic component, though its use to the structure is less obvious. Possibly the random nature of the attention deficit mind mimics the random changes to DNA that drive evolution. It may introduce the only form of creativity internally available to the oligarchy, as the oligarchy has to obtain all of its ingenuity from the normal mass of people; people the oligarchs cannot trust because of all they have done.
The oligarchy has continually leveraged technological evolution to expand its control to offset the natural enlightenment of a continually modernizing humanity. Today the annexation of technology is so complete that entire Information Society is skewed to obscure the mentally dysfunctional reality of humanity's controlling elite. The oligarchy has corrupted morality by confusing its meanings to focus society on a singular task of empowering the empathically defective, what is often called "the high-functioning autistic." Initially these misconceptions were forced on the native and natural by the Roman Church; now even socialists work to convert sadistic children into future leaders and healers.
The most recent strategy of using anti-hate as a weapon of hate against anyone or any group that attempts to resist oligarchy's inhumanity. It followed the successful destruction of the last the slavery societies, South Africa, when democratic peoples effectively politically forced South Africa's economic isolation causing Apartheid's collapse.
Other biased groups preceded Capital's conversion pure hate to a hybridized anti-hate hate; the most biased group of all, Feminists, successfully converted the struggle for equality in democracy to equality in the oligarchy; these women were the only of the socially rebellious to benefit from the global expansion of Capital. The Western oligarchy has internally incorporated equality within their structure and for themselves in a way that allows it to bond with oligarchic structures from regions that were former competitors. But the peoples of these regions are forced into fierce combat for resources made increasingly scarce by Capital's continuing growth; and any complaints from the lower productive levels can be dismissed as racism. In their minds, they can plausibly deny their bias with the most absurd rationale; they and only they deserve to be elite, as only they are unbiased. Of course the normal average person, upon hearing that, will obviously think them insane, but will be frustrated as the oligarchy has now, more than ever, dominant control over all of valid humanity.
