One of the things I focus on is "political affect." It's a multi-valent concept; one of the registers in which it works is psycho-somatic effects of political economic conditions. This article summarizes research which details the bad health effects of chronic job insecurity:
Research shows that the purgatory of job insecurity may be even worse for you than unemployment. And it's turning the American Dream into a sleepwalking nightmare. From young temporary workers to middle-aged career veterans, Americans are being pushed to their physical and psychological limits in what has the makings of a major national public health crisis.
To turn this back to politics in the restricted sense, we should recall the classic distinction between anxiety and fear. Anxiety is free-floating arousal; fear is targeted. You're anxious about the dark and afraid of an approaching attack dog.
Consider then the brutality of contemporary US politics (and don't be so smug, my non-US friends; it's coming your way, sound bites and attack ads and all). If anxiety is worse than fear, anxiety-gripped people will be prone to accept the bogeys on offer by politicians, because at least you can focus your fear / hatred on a bogey, whereas with systemic insecurity, all you can do is suffer. So better to focus on some chimeric Islamomexikenyanian-gay-sex-having-and-abortion-loving-latte-sipping-arugula-eating-unionized-public-school-teacher-cultural-elite-who-are-sapping-and-impurifying-our-precious-bodily-fluids than to have to think your way through the anxiety to the social system that makes you insecure.
Or better, the contemporary political discourse blocks the path to an intellectual understanding of systematic insecurity by its relentless individualism and shaming, its victim-blaming. "Insecure? what a loser! You should have picked a better career."
