Without doubt, they shouldn't shut down economy. Did it had any benefit? Why no one is looking for adverse effect that this economic shut down gave to us? Nowadays it's very hard to get blood for transfusion for those who really need it. A lot of people had lost their jobs and in overall life of quality is decreasing because of fall in economics and I want to mention again that your health and wellbeing depends on economic situation too, they are linked on each other so saying that why do I need good economy if I die because of corona virus, then I want to remind you what I said above + you can build immunity to COVID-19, not to hunger.
So it doesn't worth to shut down US economy again, in any way it's not a deal and majority of people won't be able to handle it and on long term this pause will bring us a bad future.
Do not close the economy. This will only lead to more decline in the economy. And people will be sick. I think that the authorities understand the complexity of the situation, and what decision they did not make (leave quarantine or leave it), everyone will condemn their action.
