But NGO's are not profit making institutions collaborating with companies like Telenor, Danone etc whose main objective is maximizing the profit.
Social Business is just a fancy term to describe normal Corporates, some of the rules of this so called social business are more ruthless than normal corporates.
Here's the first principle of social business which Grameen violates :
Business objective will be to overcome poverty, or one or more problems (such as education, health, technology access, and environment) which threaten people and society; not profit maximization
Only in your social business, if the borrower chooses to withdraw, he will only get the investment money back, not the dividend or profit. Although he had to pay the high rate of interest all along. Once he borrowed money from Grameen, he is forever stuck.
Investors get back their investment amount only; no dividend is given beyond investment money
When investment amount is paid back, company profit stays with the company for expansion and improvement
