> In a rich country this might mean paying for childcare so you can work. Your expenditure has gone up, but you are only better off by the increased post tax income less the cost of childcare. Even worse is paid childcare has substituted for family provided (e.g. grandparents) childcare. That's a pretty clear illustration of the myopia of excessively quantitative economic thinking. The economist looks at easily-quantified numbers: WAGES - CHILDCARE_EXPENSE = POSITIVE_NUMBER, and concludes "PROFIT! EVERYONE WINS!" But the hard-to-quantify negatives are completely ignored: the poorer relationship between the kids and parents, negative psychological effects on the kids due to day care, etc. That's especially true when talking about things in aggregate.
