Got no home: Naipaul's immigrants and others

The two short stories in V.S. Naipaul's book (which evidently was mostly a novel or novella) In a Free State (brought together in the Everyman's edition of Naipaul's Collected Short Fiction) present two parallel takes on the immigrant experience: in one, an Indian servant comes with his "sahib" to Washington, D.C., essentially escapes or skips out on his "master" and takes up a life of near poverty and exile working in a restaurant - when he's afraid he'll get caught and deported, he presents himself to a black woman with whom he'd had a brief and unpleasant sexual fling and asks her to marry him, which would provide him with secure residency status. The 2nd, Tell Me Who to Kill, is about a Trinidadian (presumably) immigrant to London who lives in extreme poverty, sacrificing everything and working hard so his brother and flatmate can get an education; it becomes obvious to him at last that his brother is not studying anything, just wasting time and money. The older brother then loses his savings in an ill-fated investment in a curry shop. Ultimately, the younger brother gets married to a white British girl and the older brother, the narrator of the story, is left with nothing - though there's an implication that he's involved in a relationship with another man. So both of these stories present the bleakest and darkest version of the immigrant experience - not the great American (or British) melting pot story, but an immigrant crushed by poverty, racism, and indifference, confused like a stranger in a strange land, angry and embittered but with no clear or evident outlet for the anger (see title of the 2nd story). This India-immigrant experience completely different from that of, say Jhumpa Lahiri or Rohinton Mistry - Naipaul's descendants, the children of the educated immigrants who've made it though never quite assimilated (as their children do). If Naipauls stories, from the late 1960s, have true spiritual descendents, they would be the immigrant fiction of Andre Dubus (House of Sand and Fog - Iranian immigrants), Lorraine Adams's Harbor, or Andrea Levy's Small Island - though each of these is far more political and nuanced than Naipaul's stories (to be fair, that's also a comparison of novels v stories). Interesting that, through the 1960s, Naipaul didn't write about immigrants that were in any way like him, though In a Free State includes two short essays, nonfiction apparently, that have a narrator much like or same as Naipaul observing travelers who don't fit in among other tourists.
