Life in general is full of unfair advantages or disadvantages form birth. Nobody is ever equal, equality is a made up fiction, and in a competitive environment without strictly enforced rules, cheating is sometimes just the norm. If you don't cheat, you'll be outcompeted by those who do. Statistically, the more unscrupulous people behave, the more likely they are to get ahead in life. Look at politicians, CEOs, big business owners, etc.
