Choosing an economics major means not choosing any of the other subjects. Since modern economics is focussed on greed and selfishness, it seems perfectly reasonable that not spending time on other parts of the human experience would lead to a paucity of spirit.
Modern economics is not necessarily focused on greed and selfishness. As the article mentions, the field of behavioral economics includes motivations such as fairness and altruism. And behavioral economics is increasingly popular.
It is entirely possible to choose to studying economics precisely because it is an attempt to quantitatively assess human behavior and motivations, even those that aren't greed and selfishness.
I chose to study economics (in graduate school) because I wanted to make the world better, and I discovered that the non-economists I studied from as an undergrad (in "development studies") were less convincing than the economists they critiqued.
One of the main goals of economics is to provide advise for government policy to make society better off (by some average of human well-being). I would say it takes more spirit to choose the discipline than can and does do this, than to fall for shallow critiques from outside the discipline.
You do realize you're begging the question by simply asserting that economics is the discipline that makes the world a better place and that critiques from outside are shallow?
Not so much begging the question, but making an assertion that I don't have space to prove. How could I prove that modern physics is correct to someone who had perused a physics textbook and concluded it wasn't worth serious consideration?
