In fact, it is precisely because of the inequalities that we observe in this world that we believe in karmic influences (over several life times). They equalize everything over time such that eventually everyone reaches the same goal. The inequalities of today are only temporary and get ironed out eventually.
I see, so even the claim of 'what goes around comes around' is subject to 'cosmic woo' enough to make it a) unmeasurable, b) unfalsifiable and, therefore, c)unimportant.
The 'randomness' that science attributes to everything is so...unscientific....! 
I don't think science alleges 'random' lightly - the only thing, currently, that I'm aware science considers to be fundamentally random is quantum fluctuation, and even that is only random within a tightly constrained set of possible limits. There are a number of complex interactions which science can explain the theory of the components of, but which are large enough in scope that we don't have the computational capacity or sufficient information to practically determine, and so treat as random (for instance, elements of meterology), but there's very little out there that's actually random. And yet, ironically, given that everything's underpinned by quantum fluctuations, everything's potentially susceptible to randomness - you could probably find a spiritual aphorism to make that sound deep and add absolutely no practical value if you tried.
