I agree, but that is in an newspaper article written in 1999, not in the source alluded in the original post (“In 2009, Peter Singer claimed that you could save a life for $200… [t]he number was already questionable at the time.”). When Singer takes a closer look at the estimates, as he does in The Life You Can Save, he reaches a more conservative and nuanced conclusion.
