If COVID-19 was allowed to run rampant over the United States imagine the destruction on healthcare, supply lines, commerce, etc. The answer is nobody really knows what the alternative is, I can easily imagine an economic destruction model happening without the lockdowns as well.
At best I hope our lockdown, be it until April 30th or longer, is utilized as a pause in order to get our public health sh!t together. Have a real plan for our (hopefully rolling) end of lockdowns with testing capability scaled, a real plan for quarantining the sick, mask distribution, and some real evidence of a "flattening of the curve" of hospitalizations, ICU admissions, and deaths.
