> Another interesting question is, what is the economic impact of those high risk people not being able to leave their homes? What happens to the schools and workplaces where they normally serve?

Exactly. This is something I've pondered in thinking through some of these proposals - if one wanted to pursue these policies and actually protect high risk folks, that alone would likely have significant impacts.

E.g. KFF estimated that a quarter of workers are at high risk of severe illness with Covid - https://www.kff.org/coronavirus-covid-19/issue-brief/almost-... - of course, some of these folks will be in jobs amenable to work from home. But, for the rest of them? That's a lot of the workforce either a) temporarily leaving the workforce (oh hello, economic consequences) or b) staying in, and accepting the increased risk from community spread (oh hello, more death).

> That is a rather coy statement. They don't even give us a clue how that could actually work.

Yep, lots of hand waving in that one. It's hard to take this declaration with any seriousness given the lack of substance.
