The correct answer to this open question is the following.
Develop an argument that explains if the national government should or should not make a national mask mandate based on the foundational idea of federalism.
No, the national government should never impose something like this to the United States citizens. This issue of the pandemic has been so controversial since the very beginning. Some medical doctors suggest the benefits of wearing a mask, as well many other doctors refer to the negative points of wearing the mask and how it creates other kinds of problems and possible diseases.
Based on the concept of federalism, what the US government had to do is to invest in a much better public health program that can offer medical service to the citizens of the United States in the case of pandemics, to better control, attend, and limit the spread of the disease and help heal the ones infected.
