I believe that social entrepreneurship is a temporary form of entrepreneurship and that over time we will no longer need the adjective "social" to differentiate a form of entrepreneurship. With education companies will come to serve a wider range of stakeholders and provide more "social" benefits. Should such a realization be achieved, perhaps that will quiet the critics of capitalism. Such critics claim that capitalism is immoral.
The Institute of Economic Affairs has a well written defense of the morality of capitalism in "Free market capitalism and morality". The article has some excellent citations from Adam Smith's writings. If I could figure out the legal issues, this is the first article in eight years of writing this blog where I would just reprint the article.
