In his final FinancialTimes column, “Undercover Economist” Tim Harford reminds us of two necessary factors about GDP per capita and financial progress: they aren’t a measure of well-being (consider the oil plutocracies of the Center East), however they’re strongly correlated to the person well-being. Particular person well-being is after all the one factor we must always, and even can, care about. Whereas expressing some applicable caveats, Harford makes the 2 necessary factors as follows (“Liz Truss’ progress frenzy», September 30, 2022):
Gross home product will not be, and by no means has been, an try to measure the well-being of a society. …
Nonetheless, it’s placing how nations with excessive GDP even have fulfilled residents. Select your subject, from life expectancy to toddler mortality, alternatives for girls to safety of primary human rights, cleaner streets, diminished crime, even higher artwork, from tv to the opera.

Having a excessive command of products and companies will not be a enough situation for particular person happiness, but it surely usually helps.
Notice that Harford doesn’t criticize Liz Truss, the brand new British Prime Minister, for specializing in financial progress, however somewhat for neglecting a few of its important and constitutive circumstances:

On the subject of the advantages of commerce—whether or not home or worldwide, it would not matter—bear in mind James Buchanan, who expressed a really Smithian concept (James M. Buchanan and Richard A. Musgrave, Public funds and public selections: two contrasting visions of the state [MIT Press, 1999], p. 245):
If I observe somebody with apples and another person with oranges, I do not imply to attempt to say {that a} specific break up of oranges and apples in a single finish place is healthier than the opposite division. If I watch them commerce with out making errors, what emerges, emerges, and that is how I outline what’s efficient.
