I&#x27;ve never bought the idea that welfare recipients would bear children strategically. Surely after the first child, they&#x27;d realize that this was a difficult way to increase their top-line income.
Not sure where I&#x27;d look for data on this, but my gut feeling is that poor people who have a bunch of poorly-cared-for-children get pregnant because they&#x27;re bad at planning ahead, not because they&#x27;ve been inventivized by a subsidy.
