I finally get it. Niggles are the dumb kid in class that can, (after serious effort) do the addition in your double integral. So while most people would call them useless, you've got the few bleeding hearts that tell them how great they've done and how important their contribution is. Even though the nog knows deep down they're light years behind being capable of any meaningful contribution, they'll take the praise and pretend they've done something important, that they've made some indispensible contribution.
Just like the movie about the negress that figured out how to get to the Moon for the dumb white engineers, Black Panther preys on the same common fantasy ubiquitous among blacks that they have something indispensible to contribute to the world. Because think about how it must feel to be sentient enough to realize your race is overall mentally inferior, but not be smart enough to change that fact. It would be nice to embrace the fantasy that you had done something to contribute to modern society, even though everywhere you look you see glaring incompatibility with your race.
But blacks have made one meaningful contribution to society throughout history, and that is physical labor. But that's not unique; it's the same as every other race. So they fervently embrace the farcical notion that they're somehow integral to modern society, and thus any fantasy that plays to that notion is bound to be successful among them.
I figure once they catch on they'll do what they always do and riot. If they catch on...
