Someone should do "How to take over the world!" if you woke up 50 years ago.
there are many novels & mangas about that.
the first 80 chapter of a 'reborn trope' webtoon called 'past life returner' are about taking over the world using finance/politics.
but in practice I don't think there's much to say. you don't need knowledge about the past/future but about the causality graph and how it was traversed in your previous life so that even when you change things you know how the new state will look like.
The books & amazon show "The pheripheral" has the most realistic looking way for how to do this (that I know of).
This is because the "timeline knowledge" quickly breaks and because the character went to university in his past life he is destroying kids his age making him look smart.
