From afar, the biggest problem looks like the CDCs iron clad grip on test kit certification slowing the response by a month. This compounds a general view of mine that the American healthcare system is crippled by existing regulation that links insurance to employment. Linking emergency response funding to employment is another terrible idea that will hardly assist the situation.
What everyone needed was a disaster preparedness plan. Forcing companies to pay money that they are probably not going to have in a pandemic is a great way to obscure from people how much planning they need to do. Companies don't have magically deep pockets.
