As inequalities become wider, marginalized and excluded groups face growing deficiencies in opportunities to expand and apply their capabilities and to influence the institutions and policies that determine the subsequent distribution. Antipoverty programmes have been opposed in some countries because they do not benefit the middle class, an important political constituency.150 One result is that redistribution programmes can have limited coverage among the poorest population and exhibit substantial leakage to the middle class and elites. Some programmes tie eligibility for transfers to employment in the formal sector in order to gain the support of the middle class.151 In Tanzania distributing vouchers for agricultural inputs disproportionately benefited the households of village officials, who received 60 percent of the vouchers.152 These approaches increase political support, but miss those who are most in need of support.
