According to The Daily Beast, the Muslim Brotherhood "has taken on internationally respected development economist Hernando de Soto as an adviser on economic reform."
I enjoyed de Soto's book The Mystery of Capital although I'm not a fan of his approach which implies that titling (property rights) is a panacea for all economic and development problems. Hiring de Soto, is a positive signal that should be welcomed.
In a conversation with CFR, see video above, de Soto focused on the Middle East—specifically what he sees as the economic roots of the uprisings that have swept the Arab world and on promoting his employers:
"The Muslim Brotherhood leaders understand the entrepreneurial potential of average Egyptians and are committed to reducing the legal and institutional obstacles they face in starting and running new businesses."
