This essay by Australian economist Cameron Murray is superb. A slice:

The investments that make people live longer are not usually direct healthcare investments. They are instead things like clean water, dealing with city waste, functional sewerage systems (hệ thống nước thải), reducing urban and local pollution, and clean food supplies. These have been proven time and time again to be what makes people living longer.

Now consider the cost of locking down India. Each year investments in these types of basic services create enormous health improvements of around 0.25yrs of additional life expectancy across the population (i.e. every four years life expectancy increases one year). Delaying this process with lockdowns is hugely costly there. A one year delay costs 0.25 life-years x 1.37 billion population = 342 million years of life—an astronomically high figure compared to even the worst-case COVID death toll.
