The answer is that they are all products of classic psychopathic behaviour, or if you like: psychopaths have initiated all these actions; Psychopaths in places of critical decision-making; Psychopaths in high places.
At 5% of the population, there are AT LEAST 16 Million psychopaths in the USA alone -- most are, at first, effectively clinically undetectable from the main population. The few, who are incarcerated in institutions, and available as clinical objects of study, represent the "failed" psychopath -- the one who has been "found out" by the system. Most have not only gotten away with their pernicious and predatory tactics on humanity and the planet, but have actually prospered in power, money and position.
The true effect of 16 million psychopaths on US society, its structures, dynamics and even its goals appears to be lost in the dense forest of competition, chaos and sophistry that continually surrounds us on a massive scale. But this brings us to my point: It's in fact this "dense forest" of competition, chaos, sophistry and ultimately destruction that is the TRUE EFFECT of the psychopath and provides his "home" environment and his selectively nurturing matrix; in reality, a perverse, self-generating mental ecosystem.
Allow me to extrapolate this issue from an even more forthright perspective? ALL of the primary structures, processes and objectives of our societies that have evolved through history have arisen insidiously and opportunistically from the minds of psychopaths and they all overwhelmingly favour and support their behavioural characteristics and tactics.
This leaves the non-psychopathic or empathetically developing members of society with few choices:
to move towards the edges of the psychopathically compromised society and attempt to develop an authentically human existence of creativity, mutuality and prosperity;
or to criticise and act against every perpetrated psychopathic injustice while trying to tweak the morality of the system;
or to simply continue to tolerate and compromise, mimicking a sufficient number of the psychopath's tactics and behaviours to survive in the competitive environment then trying to offset this affront to conscience by practicing gestures of mutuality with family, friends and neighbours.
These choices and their dynamics have produced the patterns of behaviour between psychopaths and their host communities for millennia. Fortunately there may be other alternatives
Let's look at an working ontogenic hypothesis:
Humans as primates are hardwired to develop somewhat mutually beneficial relationships. Humans have psychologically developed to define, explore and even codify the nature of these relationships. Part of our "preparation" for exploring these relationship potentials comes from our infancy; our high dependency years; where being incapable of providing for ourselves or for successfully interpreting the world around us causes us to meet such needs via an intermediary or mediator, more likely our mother.
Gradually those initially dependent relationships should ideally psychologically mature and transform us through increasing degrees of independence and self-sufficiency, tempered by our memories of own experiences of infancy which help us retain and develop an empathetic gratitude and an authentic understanding of discerning and meeting the needs of others.
The psychopath, through some probable peri-natal or early infancy psycho-neurological trauma, compounded possibly by a genetic propensity becomes locked into the infantile cognitive-emotional template and never moves down the path of developing empathy through exploring mutually beneficial relationships.
The psychopathic mind severely limited by the infantile cognitive/emotional template depends on amplifying the mind tools immediately useful to it, the significant ones being:
Associative recall; with some minor Functional Association; The "monkey see monkey do" mimicking faculty; and the primitive capacity for manipulating potential intermediaries in his environment through emotionally invoking their intervention.
