I would respectfully remind you that Ted Kord exists.
Paragon also said that while he is a brilliant inventor and scientist he can also become easily distracted and is much more happier and productive working in a lab rather than attending business meetings unless it is to present some new invention.
OL needs to find someone that can focus on the business side of things while Ted works on the tech side.
Roulette seems like a good candidate if her work with Sybarite is any indication.
She is cunning, skilled, ruthless, and unlike Luthor who is possibly more of these things, she lacks his issues and is primarily interested in making money, and seeing as new advanced technologies seem to be hitting the market she could want to get into that pool to make herself rich.
OL can count on her to run the business, count on Ted to make new tech and he can make sure himself that they advance the planet
EDIT: I red your edit, but the problem with that is that some of those leaders than can emerge could do more harm then good in the long run.
Like say Vandal Savage, who apparently bought the rights to the Cosmic Converter technology and was sitting on them to spite his old foe in an act of petty revenge and is now releasing it.
This act, while it may improve society, is also giving the caveman more power. Power that he in his stupid caveman brain will most likely misuse in one of his crazy schemes that he is convinced is the height of his 'wisdom', thus harming society.
Though this isn't OL's fault as he doesn't know who really owns the rights to the tech and just thinks it is Stagg Industries that does, not knowing it is really Savage.
The same can happen with other leaders who may try to follow OL's method, but in a halfassed way than can easily harm society.
