What do you think of Dr. Muhammad Yunus' vision for eliminating homelessness and poverty?

Nobel Peace Prize winner Dr. Muhammad Yunus came up with the modern concept of microfinancing as a way to help those in extreme poverty in the third world start small businesses, thus empowering them to lift themselves and ultimately their community out of poverty. From his vision statement on the Web site, “Muhammad Yunus’s vision is the total eradication of poverty from the world. ‘Grameen’, he claims, ‘is a message of hope, a programme for putting homelessness and destitution in a museum so that one day our children will visit it and ask how we could have allowed such a terrible thing to go on for so long’.”

How do Ayn Rand acolytes view encouraging such entrepreneurship? Is this an idea both the right and left can agree on?
