Perhaps if the federal and state governments had sold the lockdowns as necessary to eradicate the disease, rather than a means to flatten the curve specifically to avoid overloading the hospitals, people would be more willing to remain isolated.
But people are looking around at empty hospitals, seeing nurses and staffers actually getting laid off due to lack of need, and thinking to themselves-- well, I guess we did it. We flattened the curve and didn't overwhelm the hospitals. Job well done.
If eradicating the virus by preventing ALL spread, for all of eternity, was the goal, then they probably should have stated that at the outset. Americans are goal-driven, and outside of hotspots like New York, the goal has been achieved.
