If the money was really bringing someone down so much, the problem could be dispensed with by writing one check to a charity of their choice.
The fact that wealthy people do not give all of their money away is proof that having it is better than not having it.
My disagreement with the article is simply that saying its better to be rich than not is understating it.
Of course wealth is not a panacea to the human condition. It is however a better way of living by at least an order of magnitude than the average middle class life in the harsh, socially atomized globalized economy of the developed world. At median income levels in a nation such as the US, essentials like proper health care, education and marital stability are difficult to grasp.
