How does it make sense to say that the smaller population of US deserves way more energy than the 4x population of India. Just because the US economy is better?

How does it make sense to say that the smaller population of US deserves way more energy than the 4x population of India. Just because the US economy is better? And does the better US economy enable people all over the world or just the US? If things are fair, such an argument wouldn't even come up. Of course, we don't live in a fair world. I am not saying that developing countries should just pollute as they wish. But the developed world have not been saints in this regard.
