Over 99% of Covid-19 patients are going to die in the next 100 years. If only we could add about 50-60 years to their lifespans, we could cure Covid-19!
So years saved
85+: 383k
75-85: 825k
65-75: 990k
55-65: 580k
45-55: 340k
35-45: 170k
25-35: 80k
<25: 27k
So total years: 3.4 million, an average of 16 years per death.
At $60k a year that's $200b.
At $130k a year that's $440b
As the cost to the US economy is estimated in the 10T range, it seems a poor use of funds.
However that assumes more intervention would save more lives.
With an IFR of 0.9% (even assuming no collapse in health system, but IFR estimates also overread) you'd be looking at 2.5-3 million dead overall depending how many got it. That still would come out at 5T tops, so on a financial basis better to just let it rip.
However the big assumption is that there would be no cost to economy without intervention as many people decide to stay at home, as confidence is lost and people stop spending, and that runs into a recession anyway. The 2008 recession cost $70k per person [3], that's 23T.
It also assumes that the 5T could be spent elsewhere in saving lives.
