The goal: Freedom from the control of greedy people. Bitcoin is a tool to make a direct payment without the need of a "middleman". When a small group of middlemen have taken fees while they take control over a large group of people the outcome is repeating economic depressions. Men can not handle too much power.
Bitcoin is not going to solve greed, but it can bring more freedom. As a spoon is not to be blamed for making people fat, Bitcoin is not to be blamed for making people greedy.

99% of what all internet technologies do is remove middlemen. Most of the time these middlemen add cost, corruption and inefficiency to the ecosystem that they live in. Record companies, the postal service, news and media organizations, retailers, and now banks are all middlemen that can be removed with the creation of new technologies. This new system operates with increased efficiency and creates new opportunities, but also introduces new problems. It will take time to solve these new problems, but in the end we will all be better off for it.
