However, when the wealth gap between the rich and poor people of Rapture became too wide, Frank Fontaine, also known as Atlas, sold ADAM and made charities to help the poor people of Rapture. Also, since the economy of Rapture is based on laissez-faire captalism (an economy where governments make as little changes to the economy as possible), businesses could sell ADAM to people without any laws stopping it. Since Atlas was giving help and selling ADAM to the poor people of Rapture, they would become loyal to him. Since Atlas was gaining power and tried to control Rapture, Ryan betrayed the values he built Rapture on and became a dictator. Eventually, a civil war in Rapture was fought between people who supported Ryan and people who supported Atlas. This made Rapture a very dangerous place. Many people left Rapture to go back to the surface world. Most of the people who stayed in Rapture became Splicers.
