From a widely cited defense of the Black Lives Matter synthetic meme at Reddit:
… societally, we don’t pay as much attention to certain people’s deaths as we do to others. So, currently, we don’t treat all lives as though they matter equally.
(1) Some lives (and deaths) do matter far more than others, obviously. Everyone knows this, when they’re not high, even if they usually feel compelled to lie about it. (Some lives, indeed, characterized by criminality and parasitism, are worth less than nothing — and even considerably less.) Only bizarre religious ideas could lead anybody to think the opposite.
(2) Western societies are very rapidly losing the ability to make sane calls on the point, as exceptional productivity loses its capacity to inspire attention, and the merely piteous usurps its central cultural position.
In the absence of adaptive sensibilities, life insurance premiums — or some equivalent expression of undemonstrative, practical value-processing — will have to serve as a default.
