All I can say is: " I can see it."
Yes, the Ork communities in the barrens are hellholes. Death rates are through the roof (thus accounting for the low life span.) They live in crowded conditions sleeping 6 (or more!) to a room, they drink dirty water, and survive on scraps thrown out by others. And along comes a "little" out break of pnemoania... and no medicine to stave off drowning in their own lungs.
So they organize. They set up their roadblocks of burning tires, they jack up those BMW driving wage slaves, and along KE or LS SWAT teams in their heavy armor, and heavy machine guns and "happy smiles"... and mow down those Ork "terrorists" or "gang members" or whatever (not that it matters any, they are SINless after all)
And in the end, cause they have no where else to turn, nothing work against their poverty, nothing to prove that they ( the vast majority) are not gangbanger-anarchist-murdering-raping hoodlums that the media says they are, they slink back to their diseased slums, drink their dirty water, eat the infect soy-paste until the next outbreak comes along...
No one cares. They are orks after all so why should they? They are the mentally stunted, over muscled, degenerate "Tusker", not actually PEOPLE. After all, they could go out and get a job if they weren't so lazy. And those that HAVE jobs? Well they are stupid (probably from the inbreeding you know) so they take longer/cost more to train, so why not pay them less? And then there are all news stories and how "violent" orcs are, and all crimes they are involved in/with....
(starting to see the dystopian worldview now?)
Long story short? It's Hell on earth out there, away from the corporate housing enclaves. Racism is rampant (racism as in troll/Ork/elf/etc). Life is cheap, and body tissue has value. No one cares what is happening to anyone else as long as they are safe and they don't have to see it. (in that regard, it's similar to today)
