The Indian state of Rajasthan is offering incentives for sterilisation. With a population of 68 million, the authorities feel the need to curb the birth-rate. Now obviously they are not doing so from strictly antinatal motives, but the report is interesting and relevant insofar as it illustrates how non-birthing could be made more popular by offering rewards:
(Apologies for having to cut and paste; I don't appear to be able embed links on this blog.)
When I first saw the report it was followed by an interview with a critic of the scheme who complained that it was flawed because a) women over 45 were being sterilised and were abusing the offer and b) people weren't getting "enough information" about the scheme. As for a, women appear to be giving birth at later and later ages these days, so that fails and b was just a desperate non-argument from someone horrified by the fact that a minority of people do actually choose to cut off their reproductive capacities.
Incidentally, I mailed the feature to David Benatar, who replied saying that the scheme seemed like "a sensible idea".
