The Selfish Capitalist toxins that are most poisonous to well-being are the systematic encouragement of the ideas that material affluence is they key to fulfillment, that only the affluent are winners and that access to the top is open to anyone willing to work hard enough, regardless of their familial, ethnic or social background - if you do not succeed, there is only one person to blame.
Ruling ontology denies any possibility of a social causation of mental illness. The chemico-biologization of mental illness is of course strictly commensurate with its depoliticization. Considering mental illness an individual chemico-biological problem has enormous benefits for capitalism. First, it reinforces Capital's drive towards atomistic individualization (you are sick because of your brain chemistry). Second, it provides an enormously lucrative market in which multinational pharmaceuticals (we can cure you with our SSRIs). It goes without saying that all mental illness are neurologically instantiated , but this says nothing about their causation. If it is true, for instance, that depression is constituted by low serotonin levels, what still needs to be explained is why particular individuals have low levels of serotonin. This requires a social and political explanation; and the task of repoliticizing mental illness is an urgent one if the left wants challenge capitalist realism.
