Whether the virus escaped from a laboratory or through natural means, COVID-19 would not have been so serious for the world if China had notified the World Health Organisation a couple of months earlier than it did.
The long term economic consequences of all these measures have been swept under the carpet, but cannot be kept hidden for much longer.
We are going to be in for a period of austerity (or "economic adjustment" or what ever you want to call it) much like the austerity that followed the Second World War. (Certain foods were rationed after the war that were never rationed during the war, and rationing didn't end completely until 1954.)
