This is not about abusing the circumstance to become rich and famous, so much as it's about correcting past wrongs.
This is an interesting point, and one I'm working with, slowly.
In early parts of the story I'm telling, I had feedback both from readers and editors complaining about the relatively slow rate of financial gain (which, in hindsight, seems to have picked right up and moved right along). The point for me was that (because I'd picked the character I picked, of course), financial gain wasn't the first goal. He'd lived a comfortable middle-class life. More is better, but he had a high confidence level he could do just fine, and that was 'enough'. Fixing past non-financial mistakes was the priority.
That said, the more the story continues, and the more the rest of one's life is 'fixed' (or improving, or whatever term you want - nothing is ever 'done'), the more someone with enough perspective to see larger 'wrongs' might want to do something about them, and that requires sufficient leverage. Sometimes information is enough, but there's a point to becoming 'rich and famous' that has nothing to do with being a lazy jerk and everything to do with trying to make everything better for everyone.
In my personal opinion, at least, anyone who's been alive for more than a few decades is going to look back, see a number of 'bad' events, and want to 'fix' them.
Then we get into a few things: unintended consequences (both direct and indirect), 'the cure is worse than the disease,' how one feels if the 'fix' didn't work and the tragedy still occurs, explaining it to others, and - of course - perspective. Two people with wildly different political views will most likely have wildly different takes on which things were 'wrong' - if Osama bin Ladin got a do-over, the 'wrongs' that needed 'fixing' might be very, very different from those someone else would wish to address.
Paraphrasing one of my characters: No matter what reason there was for someone receiving the miracle of a second chance (if there was a reason), it was most likely not to enable them to just be a pampered rich jerk.
