Public health professionals are only concerned with their own remit - public health/deaths, and care not a jot for the colossal destruction involved in achieving their aims. Therein lies the role for world leaders, but thus far, they are in the thrall to their health advisors, and to their scared electorate.
Interestingly enough there is growing evidence, albeit anecdotal, that the opposite is the case. When epidemiologists and others in healthcare have been asked to advise they have too often said "well you could do x, but the economic cost would be excessive". They have effectively given economic advice which they are not trained to do, and should have been left to the economists so the politicians received a balanced set of opinions. This really is a failure of politicians because in a court of law a judge would tell the medical expert to shut up and restrict opinion to his area of expertise.
We know that for several years epidemiologists have been saying DONT lockdown early and DONT close the borders. Indeed in New Zealand it was the industrialists NOT the healthcare professionals who demanded the politicians locked down and closed early. And in the UK it was only one epidemiologist who effectively forced the lockdown against the mass of 'scientists' who wanted to wait.
The result is clear to see. Those that closed borders and locked down early have eliminated the virus and the economy can recover (albeit not aviation outside the bubble). Those that did too little too late will have ongoing economic disaster and the effect to aviation is far far worse. So blame the epidemiologists and the public health 'experts' but the wrong advice was to prevaricate, not to do too much.
