Fair for whom? In what context? Compared with what other system? These questions are never entertained by those who complain about their lot in life. While it is true that much of life's material successes are due to whim of fate, sometimes, those who can adapt to the reality of their circumstance can make their own luck. The "life isn't fair" complainers are a by-product of humanist garbage that deluded entire segments of the human race with the lunacy of perfect utopia based upon enforcement of absolute values on this plane of existence.
Life will remain unfair as long as the fact of the inequality of human beings is reality. Those reformers who attempted to fix this reality of inequality gave the world French Terror, Stalinist Terror, Mao's Great Leap Forward, and Pol Pot's Killing Fields. Reformers are evil incarnate.
They tried to force equity and call it equality, human beings are not equal. Some are smarter, some run faster, some are business inclined, others make good employees... Equality gives people equal opportunities to reach their best self's. Equity tries force everyone to equal mediocrity
What does equal opportunity even mean? Does it signify a system's obligation to disburse "opportunities" evenly across its demographic? If "opportunity" is disbursed evenly, can such situation even be termes "opportunity"? The humanists, in their greedy grasp toward that which is beyond their station, imagine the world somehow denying them opportunities, rather than understand their lack of qualification for that which they covet. Monarchs and aristocrats did not employ peasants to ministerial positions, not because they were perpetuating "systemic injustice," but because they were utilizing their common sense to discriminate against unqualified candidates.
Even the Western equality before law has its limits. Citizens have different legal previleges compared with resident aliens, visa holders, and illegals. Nothing in life is equal other than death.
