> Every avoided pregnancy is economically that woman being productive back in the workforce or managing the family on a lower overhead.
> Every avoided child death [or additional child born] is 40-50 years of productive labour from that child.
Opinions about abortion and birth control aside, these two seem to be opposing calculations. If that's controversial, perhaps the conclusion should be that economic value is the wrong metric.
No, these are the right metrics.
You're missing choice. When a woman chooses to have a child, or chooses to not have a child, we ascribe the economic impact based on her intent.
Some people are net consumers and other people are net producers over their lifetime. If you abort the net consumers and invest in the net producers it's an economic gain. What's controversial is identifying who will be the net producers and net consumers that early because it's essentially eugenics.
