If we are lucky only about 20,000,000 people will die
over the years between 2015-2020
About that many will be unable to survive
when the medical system fails
It can be as high as 1/3 our population
That does not include the possibility of
biological warfare, smallpox comes to mind...
The population wide suffering will be egregious
The elderly and young will suffer the most.
I read an article that said as a percentage of the
population the number of dead in the Civil War today
would be 6 million people.
Of course we have better ways of killing people
now a days.
That would have to be deliberately introduced into the population. The only smallpox around these days sits in vials in secure labs.
