“in Japan if you test positive the hospital gets quarantined losing tons of money” is at least inaccurate, Japan has national healthcare that short-term “sales”/cash strapping don’t matter for hospitals. Economy wise there’s nothing for their corporate to lose OR gain.
Look at any government institution in the US - despite not having a profit motive, there are still plenty of incentives to grow the budget - increased influence in the government, funding pet projects,etc.
And not to mention shutting down a hospital likely means lost wages for a lot of people.
In the UK hospitals still have individual budgets, is that not how it works in Japan.
Yes, I'd expect them to be overridden in times of emergency, but nonetheless - do Japanese hospitals really have scope to spend at will without constraints?
