This is another situation where two things can be true at the same time. One truth, likely based on what we saw happening in Italy early in the pandemic, is that there was overreaction on the part of federal, state and local governments. Overreaction in the form of unnecessary lockdowns in areas where it wasn't necessary. Overreaction in the form of constructing large, temporary hospital expansions with the expectation of mass hospitalizations that never came to fruition. Overreaction in the form of discharging military personnel who wouldn't get the vaccine. The big one, at least for me, was the federal government's attempt to use OSHA to force 80 million Americans to get vaccinated.
The other truth is that some lives were possibly saved by the measures taken. Were a lot of lives saved? Probably not because Covid ended up not being nearly as deadly as we thought, but I think social distancing, lockdowns, etc probably saved some lives that may have been lost to select hospitals being overwhelmed.
Hopefully, we learned from the mistakes of Covid and will handle the next dangerous pandemic a little better.
