Some economic research on happiness may imply fairly revolutionary conclusions. Though, as Frey and Stuzer say, money does matter, like any material aid to happiness, it has rapidly diminishing marginal utility. More of virtually any product or service keeps yielding less and less incremental happiness. Consider what this does to the implicit thesis of advertising, which is that using the promoted product will make you happier.There’s also a much larger challenge. Capitalism claims to be the surest path to life, liberty and the pursuit of individual happiness. But is it? It offers a clear route to material gain, but once that gain has met basic needs for food and physical security, it influences happiness very little: those diminishing returns again. And standard socio-economic indicators of progress don’t track human happiness well. Yet any government will cite precisely those indicators to argue its case for power.
