Do the weights really affect the argument? I think Jeff is saying that being omnivorous results in ~6 additional animals alive at any given point. If an animal’s existence on a farm is as bad as one human in the developing world is good (a pretty non-speciesist weighting), then it’s $600 to go vegan.
$600 is admittedly much more than $0.43, but my guess is that Jeff still would rather donate the $600.
