The existence of slums and favelas and their increasing criminality in Latin America cannot be explained by the lack of social subsidies. In fact, quite the opposite is the case: the leftward turn in Latin America with an increase in state subsidies that promised to help poor communities has yet to ease the problems of criminality. Subsidies not only do not help or provide only weak temporary relief, but they are also used to manipulate political opinions and influence the poor particularly around election time. The successful presidential campaigns of Lula da Silva in Brazil, and Hugo Chavez in Venezuela have been run precisely on promises to the poor that for the most part were left unfulfilled. Because government subsidies are not efficient, the large problem of social unrest is not avoided.  Furthermore the poor communities in the suburbs of Paris were already receiving state subsidies for housing and education, but this did not keep them from rioting. Therefore subsidies do not guarantee a reduction in crime.
