We have no figures on how this economic recession or maybe depression will be in lives lost and those lives ruined. Until we have that info how do we make an informed decision?
As with everything else, using the data we do have available. We can’t be held responsible for that which would have been impossible to predict, only that which we should have foreseen based on available evidence.
We won’t know the full extent of the economic destruction with AND without lockdown, ever. This isn’t a “Choose your own adventure” book. This is life. We choose the path that appears best and don’t get to redo our decisions.
In life, we use evidence to make decisions.
