Social enterprises may have to balance between improving the lives of people and earning returns

How do you define a social enterprise? The traditional way of looking at it has been that any venture that positively impacts the under-served is a social enterprise. But then issues arise as quite a few commercial enterprises too positively impact the under-served. Many of these enterprises raise money from committed impact investment firms, which do not always eye their investment from the prism of the return on equity they will get. They are more bothered about the impact that the firms create.
