Oh I blame the powers that be for opening the economy up too soon. SHUT IT DOWN AND KEEP IT SHUT until you are actually able to open safely. I don't forgive them for placing short term economic gain over human life and opening up way too soon with no plan for containment.

But there is ever mounting evidence that masks are effective including for the wearer (not 100% effective, they don't need to be for public health). A substitute for shutting it down, that's increasingly a Trump administration propaganda line, that untested, it's purely modeling based on a very optimistic projection of human behavior at that (near 90% mask use - crazy optimistic if you ask me). We have actual tested interventions but are simply frankly utterly unable to do them, so we rely on seriously optimistic modeling of human behavior and hope, that and hoping for a vaccine.

Failures of testing is of course a misdirection at this point (it was true early on of course). But at this point we would have ENOUGH testing if we didn't have an exploding number cases. This level of explosion of cases was never planned. The failure was reopening too soon.
