If you ask Scott Crossfield (one of the guys with the right stuff) Wolfe wasn't very good at writing about other subjects.
As far as broad cultural/economic/political trends, I don't think there's a better ethnographer than Wolfe.
"The Painted Word" and "From Bauhaus to our House" are probably the two best, most vividly written critiques of postmodern art/architecture out there.
One of my favorite Wolfe works is The Electric Kool-Aid Acid Test.
