Socially Proactive Investing (SPI) vs Socially Responsible Investing (SRI)

In the latest issue of their magazine (which I cannot find online), MBAs Without Borders describes SPI as a step beyond SRI because it focuses not just on "good" projects but projects that try to be extremely effective by helping people help themselves or really lift people to the next level. Increasing profitability is a good thing. MEDA is spotlighted as an organization with such investment opportunities.
