What is the matter with the following claim: the good is good because of what it does for you.

Answer and explanation:

Following this quote, I'd say that whoever pointed this out was following a logical way of thinking, stating that if good things happen to us then we will be receveing a possitive outcome. That's correct. But not every single action humans do are good, or morally correct, and sometimes even when action wrong, we receive good outcomes. So that's why we say there is injustice in this world or question ourselves on why do good things happen to bad people.

Affirmate things happening to us depends on the things we do. Our course of actions must have a positive outcome for it to be considered “good” ones. Let's say we do something that we think is right, but when results start showing we realise the opposite thing; a negative outcome.
