This may be the most controversial thing I've said yet in this discussion, but the Forgotten Realms actually uses this, in the specific context of orcs, in a really interesting way with the story of King Obould founding the Kingdom of Many Arrows. Obould basically realises that the orcs are trapped in a cycle of being on resource-poor land but having a high enough birthrate that they exceed their own land's carrying capacity. This turns into disorganised raids to grab more resources which inevitably fail (except at killing off the surplus population), and constant civil war (with the same effect), which then abate until the population once more booms.
Obould then has a great idea - let's come out of the mountains and grab some unclaimed land and create a sedentary society that can support our high birth-rate. So he conquers the neighbouring tribes, welds them into an organised polity using religio-political means, and invades the area north of Silverymoon. He ends up successfully founding the kingdom, takes over a dwarven stronghold in the process, and controls a substantial patch of arable land that he begins Doing a Feudalism with his major leaders.
The kingdom isn't super institutionally strong, so you have a lot of orcish veterans who aren't satisfied with their share of the spoils of the war, orcish expansionists factions who want to restart the wars to grab more land, conservative orcish elites who don't want to lose what they've got, and true believers in Obould's vision of a powerful, united orcish kingdom full of plenty for all. Also a heterodox reading of Gruumsh and co. as supporting the new kingdom, combined with religious conservatives who believe that an internally peaceful kingdom would be a betrayal of Gruumsh's vision of orcish life.
Overall it's one of the more interesting visions of orcs that I've seen in published D&D products, that neither leaves them as meaningless brigands, expies for real world cultures, or biogenetic bad boys. That it happened in the FR, the absolute squarest D&D setting ever created, gives me hope for everyone else to be able to better it with just a dash of imagination and freedom.
