The first question we should ask is "Who gains the most?" ...
If we're setting aside any conspiracy ... no way millions of health care professions met and agreed to murder millions more ... whatever gain is to be had will need to be a gain in the normal progress of business ...
We can scratch hospitals off our list ... typically, it's the survivors who pay for the funeral expense, in this scenario we have the hospitals paying for this to insure the bodies are cremated ... this added expense is going to cut profits, yet we see dividend payments still robust ... the math doesn't add up ... not to mention all the lawsuits filed by the families when the hospital won't deliver up the body ...
The institutions of government are another poor choice ... not the politicians we elect, but the actual office that exists ... killing off tax-payers reduces government revenue ... again, though normal operations we have a loss ... and if it is the politicians doing this, why do you keep voting for them? ...
Secret societies, rogue paramilitaries ... very unlikely to have the capital to pull this off ...
Who gains by this?
