Post colonial sad sacks

I'm looking for books about people from colonized cultures living in "the West" (whatever that means, but you know what I mean) feeling some degree of alienation, sadness, displacement, etc…

It's hard to describe, but I'm thinking of books like this:

• Most V.S. Naipaul, especially "A House for Mr. Biswas" and "The Mimic Men"
• Abdulrazak Gurnah's novels
• Jhumpa Lahiri's earlier stuff, especially "The Namesake" and "The Interpreter of Maladies"
• Sam Selvon, especially "The Lonely Londoners"
• Zadie Smith, "White Teeth"
• Orhan Pamuk, "Snow"
• R.F. Kuang's "Babel"

There's a lot of representation of middle aged men in the mid-20th century in that list, so I'd love to find books outside that context too.
