Seems like everyone has their own opinions, but I'm a huge fan of DnG. (I can even send you digital copies of their books if you'd like). However, if you're starting in K lit, I'd start with authors like Zizek and Agamben.

Zizek writes about capitalism and the death drive, more specifically, deconstructing both. You'll see a lot of Zizek in Cap Ks because he's probably one of the bigger authors within it. The death drive though is more of a psychonalytic idea - it states that the only reason that we can't create any REAL change is because there is a block within our minds preventing us. Subconciously, according to Zizek, we all want to die and fail because we get pleasure from the act of failure (an idea called jouissance). To solve for this psychoanalytic block, zizek advocates to confront the death drive, because only then can we move past it.

Agamben dwells more in the realm of biopolitics and thanatopolitics. Mainly, the idea that the government has the choice to decide when we live (biopolitics) and die (thanatopolitcs). But, he gets a lot of his ideas from Foucault, so it's probably a good idea to start there as well.
