The annual death rate in the USA is 2.8m. The virus will spread throughout the biosphere and become a standard part of the human virus paradigm, like the common cold or flu.
The best than can be done is to manage and stage its extent as much as possible, to avoid overwhelming healthcare services all at once. The Japanese seem to have the same idea.
Cases should be triaged and medical resources dedicated to those aged 50 and lower, who are still working and in generally good health.
The US pension system across many states, companies, and the federal Government itself is unsustainable, so this virus may be the key to bring those programs back into proper operation. Cities like Chicago will face a huge relief as Coronavirus spreads and lessens their pension burden.
Additionally, the housing freed up could be used by younger people and families, dramatically improving the quality of life for much of society. Inheritances could be used by younger generations to invest in businesses or upgrade personal living situations.
Lower pension and healthcare expenditure will allow lower taxes, perhaps allowing the elimination of payroll taxes.
The deaths will be tragic but from a purely economic perspective Coronavirus looks like a major opportunity for Western societies to de-age. We are very lucky that unlike other Pandemics, this virus is restricted to the sick and elderly, and barely impacts the young and healthy, unlike say the Spanish Flu.
