It's simple boys. The politicians massively overreacted based on bad science and a snowball effect. Wuhan locked down because at that point right at the beginning they didn't know how serious and dangerous this virus may be. Which in a way is actually a credit to them.
Unfortunately then the next stop was Bergamo/ Northern Italy - practically the old age home of Europe - so plenty old folks get infected and die and the whole thing looks super dangerous and snowballs from there. Politicians panic since they figure they won't get re elected if granny dies and thus they blindly follow the example of Wuhan and Italy and the rest is history....
I am willing to bet the cx half of my provident fund that in the next few months we will get the data to prove that this was the over reaction of the century by elected idiots, compromised government funded scientists and histerical media. All combined to lead to the ultimate demonstration of the idiocy of crowds in this era of Facebook and fake news.
And all of this makes no difference to the fact that most of the planet will be back in business once the penny drops while HKG is still locked down and taxi drivers here still pump their accelerators like mad to an empty airport of cluelessness and despair.
