Le microcrédit est-il le faux-nez du néolibéralisme ?
Dans un contexte de mondialisation, le microcrĂ©dit pour des femmes a Ă©tĂ© largement investi par la plupart des grands organismes internationaux et de nombreuses ONG. Est-ce une panacĂ©e pour combattre la pauvretĂ© dans le monde ou une maniĂšre dâintroduire aussi les plus vulnĂ©rables dans lâĂ©conomie nĂ©olibĂ©rale mondiale ?Pour faire le point sur ce dĂ©bat, nous proposons dâaborder la question sous deux angles. PremiĂšrement, celui de lâefficacitĂ© du microcrĂ©dit comme instrument de la lutte contre la pauvretĂ©. Il semble alors quâelle est trĂšs variable et que ce sont au mieux les « moins pauvres » qui peuvent en profiter. DeuxiĂšmement, celui de lâobjectif secondaire du microcrĂ©dit qui se veut aussi lâĂ©lĂ©ment dĂ©clencheur de lâempowerment des femmes pauvres. Les Ă©lĂ©ments de rĂ©ponses sont Ă©galement divers et lâempowerment clairement constatĂ© dans certains exemples indiens semble ĂȘtre surtout lâimpact des groupes dâentraide (self-help groups), dont le microcrĂ©dit ne reprĂ©sente quâune des activitĂ©s.En conclusion, il semble que, dans la majoritĂ© des cas, la microfinance crĂ©e un filet de sĂ©curitĂ© Ă©vitant ainsi des situations sociales explosives, sans pour autant reprĂ©senter une Ă©chelle pour sortir durablement de la pauvretĂ©.Is microcredit the mask of neoliberalism? Microfinance and poor women: the story so far. In the context of globalisation, micro-credit for women has been invested by the majority of the international institutions and many NGOs. Is it the panacea for fighting against poverty or a means of introducing even the most vulnerable into the neo-liberal world-economy?In order to give an overview of the debate, we propose to look into the question from two points of view. Firstly, the effectiveness of micro-credit as an instrument to fight against poverty seems variable and apparently the âleast poorâ are the only ones who might benefit. Secondly, micro-credit often pretends to trigger off poor womenâs empowerment. The conclusions are once more divers and in some Indian cases where clear evidence of empowerment could be found, this seems to be first of all the positive impact of the self-help groups who provide many more services on top of micro-credit.In conclusion, it seems that most of the time, micro-credit creates a safety net that avoids socially explosive situations but does not provide a ladder to climb durably out of poverty
