Lifes fair, Fair to be, UNFAIR

A brief description, what is that supposed to mean?

Yeah life’s fair
Totally fair to be unfair
Because you can’t be prepared for life to be fair
Because you can’t be prepared for life to be unfair
Because you always have to learn from your mistakes
Because you’ll do, whatever it takes
Yeah life’s fair
Totally fair to be unfair
&& the mistakes you made
The things you said
Make you look forward to, make you dread
Because you can’t be prepared for the future
Because you can’t be prepared for the truth of the past
Because the futures unclear,
The past is a bit to certain, and now you try to focus on present
Yeah life’s fair
Totally fair to be unfair
What would life be if it was fair?
What would life be like?
What would you be like?
Life would be boring
Because everyone would get equal amounts
Because everyone would win the lottery
Because everyone would have the same amount of money
Because everyone would be fair, everything would be fair
Now is it fair, for life to be unfair?
Yeah life’s fair
Totally fair to be
Unfair
