Doom and gloom! The long haul! No exit strategy! Repent, the End is Nigh!!
Perleeease! This is total shite and an abandonment of common sense and a denial of current knowledge. Measured scepticism is great but pathological scepticism makes an idiot out of you.
Go back to basics and the numbers will tell you exactly what is not going to happen but what has already started to happen - I posted the Imperial College study earlier in this thread and it gives you all the numbers necessary. This is not the Black Death - i.e, 95% of the population, at least, will survive and the age mean hides an unfortunate truth for older gits (like me) in that the max 5%~ toll is more likely over 10% for the 65 and older bracket....this basically means that the largest number of deaths is going to be amongst the sick, frail and generally elderly or put another way, the demographic which contributes the least to society.
The matter of immunity has been discussed and dissected to death(!) and put simply, those that get infected and survive will develop a level of immunity however variable that may be. In the meantime, vaccines of different types are being developed and just as has occurred with seasonal flu these will start being rolled out to the general public as and when they start becoming obviously viable.
During the culling process, those who have survived will take up the threads of their lives and society will gradually get back to normal. The virus timeline is about 3 weeks from beginning to end, so very rapid and the first signs of the societal recovery will be evident in a couple of months, not years. We are all know the adage about the markets rising more slowly than they fall and this is exactly the same. The herd dynamic that makes most traders do stupid things (and the few do smart ones) operates with the reaction to the virus. Look at what will happen to the panic buying lunacy: when everyone has 6 months supply of toilet paper and pasta and people have started to adapt to the new normal, then very quickly the supermarkets will be overflowing with stuff they can't sell because those private hoards are being used up instead.
Stupidity and ignorance never go out of fashion and the virus is not going to get rid of that - but, the moment enough people start to understand what is going on then the mood will change and behaviour along with it.
