[BioShock Series] Why did Rapture fail, and how long did it last before it failed?
gpt
It failed because somehow everyone who heard Andrew Ryan's objectivist tirade about sweat ownership and how a man is entitled to what he creates missed the implication that when Andrew Ryan built an underwater city he would feel perfectly justified in taking anything and everything created by *his* city for *himself*.  

Fontaine was a clever business rival but under Ryan there was no need for rivalry, he could just raid Fontaine's businesses and seize the plasmids and Adam for himself. Naturally.  This appalled his security forces and everyone else who hadn't made the connection that Rapture's promise of individual freedom to do what's best for one's self meant that Andrew Ryan would do what was best for himself, with no concern for ethical business practices, justice, or anything else a society might expect.

Thusly cornered, Fontaine used his influence with the lower classes and considerable stores of Adam to arm a revolt of superpowered splicers to rise up and overthrow Ryan's Me-ocracy. He also took a child from a whore Ryan frequented.

By the time Jack Ryan arrived, the fighting was stalemated and most of the inhabitants were dead. Fontaine was in hiding under the alias Atlas, and using programmed mind controlled phrases he directed Jack to assassinate Andrew Ryan before commanding him to just die himself.  Jack resisted the commands and eventually confronted and killed Fontaine.
