Some of the wealthiest people in the World, the Gulf Towelheads, have done absolutely nothing to achieve their fortunes, the oil was simply lying under their feet in the ground, and they didn't even have to get it out themselves, - probably "fair" (and lucky).
The indigenous peoples of South Africa were also standing on a fortune in diamonds, gold, precious stones and minerals but others got rich on it and got them to dig the stuff out, to boot. They are still poor, - definitely unfair and unlucky.
