Yes, If it’s earned.

Don't worry I'll avoid my own version of the "life is unfair rant". ( I typed it and erased it. I'll try to stick to the question.)

No, certain advantages are intricately fair. Earned advantages are fair, but not always realistic and earned upon an even playing field.

For example, in situations where better preparation led to better performance. If I studied longer than you and I got a higher grade then the edge was fair and understandable by both parties. However, the playing field may have been leveled due to complications at home, stress levels, and differences in physical/mental health. But studying harder and getting better results is a logical progression of events. One that cannot be argued against at face value.
