Again, I dips me lid at your exquisite use of language, Mick:
An estimate of the value of statistical life that has been discussed here is around $5 million. I've estimated that we've probably spent somewhere between 2 - 3 times that per life notionally saved. A factor of two or three is at least 30 times less than 'orders of magnitude'.
I'll assume that your estimates are accurate. But...
It's of course your estimate of what's probably been "spent". Never an acknowledgement of the costs that you don't measure in dollars because you don't want to.
