Rapture was built by a man named Andrew Ryan. Andrew Ryan believed that the governments and religions above the ocean wanted to take away the wealth from people who worked hard for it and to give it to so-called "parasites", people who take away things from people who worked for it. He wanted Rapture to be a place where people could become anything or do anything they wanted if they worked hard for it, a place where science could develop quickly because religions could not enforce morality to slow down or stop scientific research, a place where artists could make any art they wanted because governments could not censor their ideas, a place where rich and powerful people would not be forced to give anything to poor and powerless people.
