I'm not much of a Glasweegee fan…IMO his apparent contempt for his subjects is too blatant. Martin Parr, I think, negotiates the amusement-bemusement-disdain nexus more effectively.
Even better is Edward Burtynsky. Now much of his work is "landscape" but his aim is very different to most photographers working in that arena. His current book, Water, is a fine case-in-point. Striking, often quite beautiful, photos of…pollution. He just takes the photos & presents them, leaving it up to you to realize what they are and what you think—if anything—about the larger issues involved.
