It is as they are now saying, 'health or wealth'. Why some people seem to think we can 'ease open' without an increase in cases I don't know. Opening up comes at a cost in lives, there is no way to avoid that.My prediction is there will never be an effective vaccine.
Assuming that herd immunity can be attained, what with "social distancing" and "flattening the curve" it will take at least a decade to achieve. Just take a look at the world population (or just look at Canada if you like) and the numbers that we know of that have been infected already. Minuscule. Those puny numbers will hardly bring about herd immunity. So lockdown will be the order of the day for at least 10 years, unless we get sensible and decide to allow nature to take her course. I also predict that will happen because too many will become disenchanted with the effect of lockdown on the economy and on life as we know it in general. Further, I don't believe government can sustain CERB and all the other handouts for a decade or more.
All the present talk about re-opening the economy is just plain silly unless one agrees to a lot more infections. After all, what has changed in the past few weeks to suggest that we can now ease restrictions without feeling the lash? Absolutely nothing.
I just hope you are wrong about a vaccine. Without it, I cannot see the economy ever recovering and in fact expect it would continue downwards until some kind of final collapse and we end up with total anarchy before we can reach 'herd immunity' assuming that it exists, there is no guarantee of that either.
