For the script of his "Banker to the Poor", written together with the famous Sergio Donati, Amenta was awarded and praised by Robert De Niro at the Tribeca Film Festival. Italian producer Simonetta Amenta purchased the film rights to the story through her company Eurofilm - before Professor Yunus won the Nobel Prize. In Muhammad Yunus' early efforts to alleviate poverty in the regions near his home, he worked to improve local farmers' crop yields. Though he succeeded in his short-term project goals, he discovered another problem: a whole section of Bangladesh's poor had slipped through the cracks in poverty reduction programs. To combat that problem, he researched the poor in the village of Jobra, later redefining the previously vague 'poverty' and developing and studying categories of 'poor people.' In "Banker to the Poor", Yunus writes: "I found it useful to use three broad definitions of poor to describe the situation in Bangladesh: Watching the poor in each of these categories, he discovered that slightly impoverished citizens who were eligible for aid crowded out those who desperately needed aid. When Yunus started Grameen Bank, he tailored its programs toward these desperately poor. Some people disagree that Yunus' approaches are the best possible way to address poverty or microfinance. For instance, Milford Bateman with the Overseas Development Institute wrote, "When microfinance-funded enterprises are set up, they tend simply to displace other tiny businesses without funding, meaning there is generally no net impact on poverty." Bateman also contends, "It turns out that as more and more microenterprises were crowded into the same local economic space, the returns on each one began to fall dramatically. Starting a new business or a basket-making operation or driving a rickshaw required few skills and only a tiny amount of capital, but such a project generated very little income, because everyone else was pretty much already doing exactly the same things in order to survive." In Yunus' attempt to help the absolute poor (which is different from the 'nonpoor' or middle business sector of the economy), Bateman argues that he inadvertently crowded out this vital middle business sector, hurting the absolute poor to which he devoted Grameen's efforts. Bateman further argues, "To the extent that local savings and remittance income are increasingly channeled into such simple activities via microfinance institutions, and so channeled away from more sophisticated and scaled-up activities associated with small and medium enterprises, the more the economic structure of that country, region or locality is inevitably undermined and destroyed."
