Tom Jacobs flags a series of experiments that suggests our habituated consumerism – our ingrained view that we can choose our fate – undermines aid for the poor:
After taking into account social class, gender, and political orientation (all of which can influence one’s attitudes on this issue), those who had been thinking about choice were less disturbed by the examples of inequality than those in the neutral condition. … The psychology here is clear enough. One’s success in life is determined partially by one’s life choices, and partially by forces outside of one’s control. If the personal-decision part of that equation is front and center in our minds, we’re more likely to negate or downplay the societal factors that limit one’s options.
