Currently I'm reading the book "Social Business" by Muhammad Yunus. Not finished yet, but so far it is worth reading, imho.
The concept and principles of "Social Business" make a good impression:
"Yunus Social Business believes in the power of business to end poverty. Our Philanthropic Venture Funds finance and support social businesses in developing economies, whilst our Corporate Innovation guide multinationals to apply their core competencies to some of the greatest human challenges."
That's why I'm proposing investments in social businesses.
