According to the Gallup-Healthways Well-Being Index, in the US,
Taller people live better lives, at least on average. They evaluate their lives more highly, and they are more likely to report a range of positive emotions such as enjoyment and happiness. They are also less likely to report a range of negative experiences, like sadness, and physical pain, though they are more likely to experience stress and anger, and if they are women, to worry. These findings cannot be attributed to different demographic or ethnic characteristics of taller people, but are almost entirely explained by the positive association between height and both income and education, both of which are positively linked to better lives.
So should we start taxing taller people for the sake of equality? That is what Greg Mankiw suggests a Utilitarian should want. He explains,
If you are going to take that [utilitarian] philosophy seriously, you have to take all of the implications seriously. And one of those implications is the optimality of taxing height and other exogenous personal characteristics correlated with income-producing abilities.
A moral and political philosophy is not like a smorgasbord, where you get to pick and choose the offerings you like and leave the others behind without explanation. It is more like your mother telling you to clean everything on your plate. If you are a Utilitarian redistributionist, the height tax is like that awful tasting vegetable your mother served up because it is good for you. No matter how hard you might wish it wasn’t there sitting on your plate, it just won’t go away.
In his paper on the height tax, Mankiw concludes,
Our results, therefore, leave readers with a menu of conclusions. You must either advocate a tax on height, or you must reject, or at least significantly amend, the conventional Utilitarian approach to optimal taxation. The choice is yours, but the choice cannot be avoided.
