Zizek discusses how our current system of capitalism, which injects a strong element of charity into the system, is actually worse than leaving the charitable elements out. Pulling an example from our distant past, he suggests that the worst slave owners were the ones who were nice to their slaves as such nicety eliminated reasons for the slaves to reflect on the horribleness of their situation or to have a workable desire for freedom. Zizek suggests that we should rebuild society in such a way that instead of giving relief to the immediate problems, that we find ways to minimize the causes of those problems (prevention instead of charity).
