I find myself reconsidering the original proposition by England to isolate the most vulnerable for a couple months and let the virus work its course through the less vulnerable population.

If death rate is substantially lower among the under 50 crowd, this could work its way through with a fairly low death toll, and result in a herd immunity within a couple months. This slow burn approach we're doing however seems possibly to be the precise worst way to handle it, leaving the virus in the population for as long as possible, reducing the ability for our vulnerable population to avoid it.

Note I think the best possible solution is a complete lock down for a couple months until the virus is more or less eradicated, as Wuhan did. But I don't think it's a realistic option in our society.
