And don't ignore the long term impacts either. Just because you the U.S. has a low mortaility rate does not mean the disease will not have long term effects. People may die sooner, or suffer significant health effects later on that leave a lasting mark on the economy.
You suggestion that this is because the US is so interconnected is a foolish one. Europe is quite interconnected, has had similarly bad initial outbreaks, but has subsequently been able to address those outbreaks much better than the U.S.. What would you say about the politicization of preventative measures that we know work - wearing masks and social distancing?
