As I understand it, virus mutations occur more with a greater pool of infected people. Therefore the newer and possibly more lethal variants are of great concern since it takes a year or more to develop a resistant vaccine. Increasing the rate of spread of the virus can promote the opportunity for viral mutations to occur.
Economics is a different topic. Of course its necessary to develop an economics program that can function in a viral contaminated social environment until the virus is nearly entirely eradicated. Loosening restrictions early could be compared to taking a cast off a broken leg too early even though one wants to go jogging. Political leadership that isn’t capable of tailoring an economy to work with virus out there demonstrates the lack of creative thought in politics i.m.o. One cannot morally just say the heck with those that will die from Covid and proceed recklessly without moving into a fascist mode, and there are of course some that are happy with that. In the movie 1900 Mussolini drives over a guy injured in the road and keeps on going untroubled. I suggested adapting Halloween masks for full face coverings so people could work and travel more safely in a contaminated environment. When I was an Army reservist I learned the method of firing a rifle while wearing a chemical mask accurately- it requires some adaptation over normal procedures. Adapting economic procedures too-change is difficult for organizations and establishments that are indignant about it. The results of failing to do so can be fatal for some.
Dr. Fauci at least seems to believe that wearing masks is a good idea. As states loosen restrictions and variants spread, Fauci warns that the U.S. could be headed for yet another virus spike.
