"Yellow Card Man", Paolo Bacigalupi

NT ASFM (Asimov's Science Fiction) DEC 2006 – science fiction
Ethnic Chinaman Tranh has lost everything and is merely surviving in the slums of Bangkok. He once ran a shipping business in Malaysia, but his family was killed and his livelihood destroyed. Now he is just another yellow-card refugee without a steady job. But he does have a fine white linen suit. Tranh encounters a rich man whom he once fired.

This story is set in the same future as Bacigalupi's "The Calorie Man", but the science fictional elements aren't as integral to the plot. This is a well-written story, but it's really grim.
