Robert Castel highlights the shifting framework of government in advanced capitalist or 'postmodern' societies. He argues that government is increasingly about the management of risk and prevention, or "the establishing of flows of populations based on the collation of a range of abstract factors deemed liable to produce risk in general." Castel suggests that this neoliberal paradigm of government launches "a new mode of surveillance" that is not targeted primarily at individuals or subjects "but factors, statistical correlations of 'heterogeneous' elements. They deconstruct the concrete subject of intervention, and reconstruct a combination of factors liable to produce risk. Their primary aim is not to confront a dangerous situation, but to anticipate all the possible forms of irruption of danger. 'Prevention' in effect promotes suspicion to the dignified scientific rank of a calculus of probabilities." Castel maintains that prevention works in tandem with the dream of invulnerability, of "absolute control of the accidental," seeking to control both the internal weakness of individuals as well as exogenous risk factors such as alcohol, tobacco, driving habits, eating habits, and so on, Surveillance of risk factors and their prevention are deemed necessary to cultivate segments of the population according to the neoliberal system of valorization, making them competitive in the global economy. Castel notes, "Instead of segregating and eliminating undesirable elements from the social body, or reintegrating them more or less forcibly through corrective or therapeutic interventions, the emerging tendency is to assign different social destinies to individuals in line with their varying capacity to live up to the requirements of competitiveness and profitability." The end result of the neoliberal paradigm of government is a "dual-track" society: "the coexistence of hyper- competitive sectors obedient to the harshest requirements of economic rationality, and marginal activities that provide a refuge (or a dump) for those unable to take part in the circuits of exchange." The changing of culture thus naturalizes the different social destinies of individuals.
