[WS:] He is not alone. No one who cannot get grants, or attract paying clients aka students can get a job in the US academia today, except perhaps as an adjunct or junior faculty at a "teaching" (translation: second or third tier) university. This is the problem that many academics who achieved some kind of recognition through their writing face - when the initial fascination with their book is over, they must either polish their grant writing skills or else step down to the ranks of academic proletariat.
Furthermore, academic disciplines have not been created equal in their grant generating potential. Social sciences and the humanities have a distinct disadvantage here vis a vis not just medicine-and-health related fields (which fetch mega grants) but also poli sci, economics, psychology or business management. What he writes about consensus building and play in the anarchist circles is a standard stuff in countless NGOs and corporate team-work training, so it is difficult to believe that it generates any establishment backlash. Ditto for "Debt" most of which is pretty respectable anthropology.
It looks like that he is paying the price for being an anthropologist and having a writing style that has zero appeal to grant managers, rather than for his association with the anarchist movement. He would be advised to follow the footsteps of a fellow anthropologist Janine Wedel who invented a new field "anthropology of foreign aid" which landed her on a faculty position at GMU (http://policy.gmu.edu/tabid/86/default.aspx?uid=88) even though she was highly critical of the sacred cows of the US policy discourse (neoliberalism, privatization, foreign aid, etc.) FYI, "anthropology of foreign aid" is concerned with the effects of informal human relations on the functioning of formal policies and formal organizations - something that is relevant to a broad audience, not just left critics of neoliberalism.
And there is also the public persona projecting the "right mixture" of authority, self-confidence, reliability and entrepreneurship that is necessary to be seriously considered for a faculty position at a top ranking US universities. In other words, applying for academic position is to a large degree a beauty contest, and the "right mixture" of authority, self-confidence, reliability and entrepreneurship is beautiful in the academia. Not having it creates disadvantages similar to not having the right look in the fashion and glamour industry. I do not know about Graeber, but I had ample opportunity to observe it as I spent most of my adult life in the academia.
