That's not necessarily clear - where he's seen the effect is in the Diaphoron, that being his own part of the community. Some degree of disaffection in the rest of Aratta's lower-class enclaves exists, but may or may not be related - it's hard to tell from speaking to spacefarers in the Xenodrome or locals in Aratta Adiaphoron, because they're part of many small communities and not one, unified froup with a strong self-identity.

If you wanted, you could look more into whether something similar is happening in the Alliance Diaphoron neighborhood, but it isn't clear from the outside, and to venture there yourself you'd have to secure a visa (which probably means looking for a job there).
