It's the difference between 400,000 dead and 1.6 million dead.
The government's strategy is 1.2 million EXTRA PEOPLE DIE than if you flatten the curve.
You can't eliminate deaths. You can save 1.2 million lives by acting early (at least, my maths was conservatively estimating only 60% of the population get it).
What economic impact is 1.2 million deaths?
They say they're following science - well it's obviously some different science than the rest of the world and WHO are using. And, funnily, it's not available online quite freely - unlike the science the WHO and rest of world are using. Why the lack of transparency if it's really science driven? It's not, it's policy driven.
It may be they're playing with a ballpark of 1.2 million extra deaths to try out nudge theory. That's not science.
