Terry Pratchett coined the phrase to describe a canon of literature so utterly negative that no redeeming virtue could be salvaged; such is the interview by Slovenian philosopher Renata Salecl in Der Spiegel.
All life is misery. There is no joy. We have too much freedom, and too great a choice. There is no happiness. There is no alternative. Capitalism is neurosis.
Yep; what we all need is a big, responsible State to make all those awkward consumer decisions for us; Can't choose between ten brands of washing machine? Let the State allocate you a place in the two-year queue for a single government brand instead. Don't shop - just receive a ration that the State decides for you. Don't think - the State will do all the thinking that's needed.
It's a lesson I suppose that some people - clearly poor Renata included - are just pathologically incapable of benefiting from freedom. Of course, Communist nations used to keep tame philosophers on the payroll. These days the buggers have to earn a living. No wonder some of them aren't happy.
