Selfish Reasons to Have More Kids
American moms spend more time taking care of kids today than they did in the 1960’s. This is perhaps the most surprising of many bold but well-backed claims in economist Bryan Caplan’s book Selfish Reasons to Have More Kids.
“According to time diaries, modern parents spend an incredible amount of time taking care of their kids. As expected, dads do a lot more than they used to. Since 1965, when the average dad did only three hours of child care per week, we’ve more than doubled our efforts. Given how little dads used to do, though, doubling wasn’t hard. What’s amazing is the change in the typical mother’s workload: Today’s mom spends more time taking care of children than she did in the heydey of the stay-at-home mom [13 hours/week vs 10].”
The major argument of the book, backed up by many twin and adoption studies, is that parenting matters much less than we think- at least as far as children’s long-term outcomes are concerned. A lot of kids’ outcomes seem to be determined by factors outside parents’ control; the biggest way parents do influence their kids long-term outcomes is through genetics. Adopted kids generally end up with education, income, IQ, and many other outcomes being much more similar to their biological parents than their adoptive parents.
In turn, Caplan draws two main conclusions from this argument. One, lay off the tiger parenting, since all it accomplishes is to make kids miserable. Two, for those who do want to influence their kids: “The most effective way to get the kind of kids you want is to pick a spouse who has the traits you want your kids to have.”
Other interesting points:
US kids are about 4 times less likely to die during childhood today than they were in the “idyllic” 1950’s. The reason people think otherwise is because Law & Order SVU has replaced Leave it to Beaver on TV (and the rise of 24 hour news, et c). Homicides actually have gone up a bit, but this is overwhelmed by the massive decline in deaths from accidents and disease.
I thought that government “child bonus” payments were ineffective at promoting fertility, but Caplan cites research showing the opposite. Same with mandatory paid leave- the possible positive externalities of extra kids make me start to rethink my knee-jerk anti-regulation stance.
IVF + surrogacy = totally outsourced babies. Any rules against mass production and/or use by fertile people? This seems like a good way for any rich person to create an army of clones.
