Lockdowns, social distancing and masking – done consistently – do work. Even the half-measures lockdowns the US has gone through has stopped the entire medical system from collapsing, and at times it has been very close. In NYC in the first wave, it did.

But that isn't what has happened in the US, largely for political reasons.

There are no good options, only less worse ones, and aggressive lockdowns have got Australia, for example, back to work. The cumulative cost of the US's failure to grasp the nettle and just shut everything down for two months properly back last March is enormous.
