Because not a single person has logically explained it that I've seen? I get the moral argument. I don't see the economic one. If I look back to the last serious pandemic that hit us, the Spanish Flu which had a lot more loss of life per capita than we're likely to see here, did the economy collapse? Even with a world war ending which usually by itself will cause a rescission an economic boom followed. The wealth of people who die doesn't vanish. It gets passed down. And opportunities open up for those who live causing wages and spending to increase on a per capita basis.

Now do I think an economic system with these incentives is fucked up and do I feel dirty typing that? Yeah. We certainly should change the system.
