At first everybody was so amazingly successful, great wife, then great kids, all doing very well, financially too. But after 10 years with each reunion less and less people showed up. Those who were missing had no wife and family left and didn't want their old pals to know how their personal lives had faltered.
You only mention careers...? Please report overall long-term life success that includes the family :)
Also, since you mention finance, while they personally benefited, and their industry did too, what about the rest of society? Does the latest microsecond computer trading algorithm really benefit mankind overall?
So to summarize, the questions I have are about 1) individual success not just "career", "financial" and "short term", and 2) that individual success from the perspective of society.
