This is not hard to model once there are a few cases in a population, again IMO.
I don't think putting out a fire has any major adverse effects, so perhaps not the best comparison.
Flattening out the infection curve too much means increasing the economic harm by a much larger degree.
Calling a lockdown a week too early, means continuing it a week extra on the other end or you risk a sudden, unmanageable peak.
I don't envy any politician the decision, but pandering to panic and locking down too soon will cause a lot of harm too.
Even putting aside the sick leave, which will happen either way.
What's the problem here?
The (totally made up number) 15-20% of greedy people who put money first no matter what.
It's really sad.
I realize my opinion may not be the mainstream one, but I think the 2008 financial crisis did more good for the environment than all the "green investments" of the past few decades.
> the stress of the main earner being unemployed
That can indeed be a problem for families. I hope the crisis will bring about some reduction in consumption/travel, downshifting, rethinking of priorities, simpler living.
