Arrogance is not always sinful, a degree of such strongly motivating attitude can be necessary for performance. It can be seen in elite sport and politics every day.
The cabal who found themselves in power when a human created monster respiratory virus became rampant across an increasingly mobile world population allowed that bunch of incompetents but well endowed with ideology, to become the greatest danger the population faced, exceeding the afflictions from the actual virus itself.

In war the plan begins to unravel as soon as the shooting starts because the human brain reacts differently to such chaos.

In WW 2 the French defence was doomed the moment the German High Command accepted the blunt force through the Ardennes was going to threaten the static defence of The Maginot Line, consisting of forts strong points and tank traps with a classic flanking maneuver that bypassed the Maginot system.

When Covid 19 or to be more accurate my Colleague Tom’s more than adequate nomenclature, Chinese Lung Rot, became noticed by health officials everywhere the Government of our naturally protected little bunch of Islands with its 12 hundred mile wide moat, as a first step abandoned the cumulative wisdom contained in the already developed pandemic response into the waste paper bin and set about reinventing the wheel with the sparse wisdom collectively available from their totally inadequate intellect.
A bunch of people assuredly educated in school rooms but entirely bereft of anything learned in the harsher school of hard knocks that most wealth creation is fueled by, immediately set about spending money and introducing controls on a population largely confused and scared witless.
I mean Teddy bears in Windows and no recourse to human sacrifice to placate offended Gods.

What was achieved, well the control was very effective and efficient from a government perspective even the inadequate Opposition was acting like a bunch of eunuchs in a brothel.
Spending reached stratospheric levels with absolutely zero to show for it.
The controls that extended to the extremely sad situation where the dead could be consigned to their ultimate end zone in an almost total absence of friends family and work mates.
Antagonism was one aspect that showed an increase as productivity evaporated and freedoms were increasingly removed.

A increasingly revealed intellectually inadequate occupant of the Ninth floor set about becoming the most reviled leader in the Nations short history as she and her coterie of close advisers, far too many shielded completely from any constraint, went on a rampage of denial of basic civil rights while occasional missteps by close colleagues went unmarked.

Now the Nation faces an ongoing clamber out of an abyss to overcome the carnage and a media who have collectively allowed their cojones to be preserved in formalin while abdicating any intent to hold Government to account continue to fulfil the demands of their socialist masters every opportunity in not questioning and demanding answers but an incoherent series of constant attacks on everything that threatens to expose the abject failings of their defeated icons.

One NZLP functionary elevated far too far above her intellectual capacity has embarked upon a criticism of The Hon Erica Stanfords moves to repair the now almost totally disrespected NCEA monitoring of education achievement. Arrogance looms large as we are informed she declined at least three invitations to participate in a collegial effort to rebuild a trusted replacement for NCEA that had depended upon far too many students gaming the system while arriving at higher education and or work place bereft of anything resembling literacy, numeracy or ability in logical process, Traits that almost every employer outside the Public service might require as basic talents in a prospective worker.

How arrogant was a deputy Police Commissioner in accessing rather disturbing images on his work computer device, actions he was presumably trained and sworn to prosecute in any citizen so discovered.

What degree of arrogance might an ex Prime Minister need to traipse around the world handing out advice on governance when she demonstrated admirably for in excess of five years an almost total dearth of any of the necessary abilities for such a role.

Then we face a current Prime Minister clinging for his political life in believing a mantra that humans can alter the climate of the world by following an impossible dream involved in zero carbon by ending using energy from coal oil and natural gas will be altered by sending billions of money borrowed to Paris when all floods, Droughts and destructive winds continue apparently unabated , and salvation will accompany “ZERO CARBON” by 2050.

So I will ask again is Gross incompetence inheritable, infectious or merely a learned behaviour and requires liberal applications of arrogance to be promulgated as policy.
