Facebook has created new jobs here in the U.S. and abroad in many countries. Just take a look at their job board: http://www.facebook.com/careers/?view=location. When a company files for an IPO, they are seeking to raise more money from investors so that they can expand which will in the end create more jobs.
Zuckerberg is trying to gain investor's confidence so that he can over inflate the company's value between $70 to $100 billion dollars. This is why Zuckerberg said "bring a more honest and transparent dialogue around government that could lead to more direct empowerment of people". In the above statement, he is saying that Facebook helped to give the people of Egypt the ability to remove their president from power which he is using to gain the confidence of investors.
Yes Facebook can help in bringing more attention and dialogue to different situations but it is impossible to claim that any company can bring direct empowerment for people with their governments.
Facebook monitors what people are saying or doing on their platform. This means the government can come knocking on Facebook's door at anytime and subpoena anyone's information. Also, Facebook has and can shutdown people's pages due to content that they deem as not appropriate.
I think Zuckerberg needs to rethink his statement of "more honest and transparent dialogue".
