Andrew Ryan had no part in Jack's mind control or "
would you kindly". He realized it was being used towards the end of his life and revealed it to Jack as part of his grand philosophy. Beyond that, he was not privy to its existence and he didn't rule with it either.
As to your points of his prowess and leadership, Andrew Ryan created Rapture based on the philosophies of an un-governed society free of censorship, governance, and morality. Ryan was also extremely naive to the effects and ramifications of ADAM, dismissing concerns of a society dependent on it. It allowed the rise of Frank Fontaine's black markets.
Ryan also was too big-headed to recognize the necessity of the "common man", choosing to only allow the brightest minds of the world into Rapture. Thusly, menial jobs like food processing and maintenance were not done and dissatisfaction rose throughout Rapture. This high-class mentality of Ryan also helped catapult Atlas, a man of the people, to the forefront of the needs of the city and made him popular among the poor. Ryan's idealistic philosophies were put into question as the needs of the city grew and the "credibility" of his beliefs were called into question.
Finally, Ryan betrayed the very theme of Rapture by nationalizing industries and becoming the very thing he sought to escape from. This move cost him allies and remaining support in Rapture, sparking the Civl War in Rapture and snowballing the events of the first
Bioshock into effect.
To me, Andrew Ryan was a man that could achieve great things, but certainly not maintain them or effectively rule. He was flawed, as many fictional and real people are, and his ideals were his flaws. He saw nothing beyond the scope of what he believed in, yet necessity and reality forced him to compromise his beliefs. The idea of Rapture was thrilling and desirable to those that felt the way Ryan did, but the reality of what makes something cohesively exist did not fit with what Rapture was founded on. Thus, it failed.
