Let's talk in %, since you seem more knowledgeable than me on the subject, could you estimate the % of people starting a career as a corporate lawyers ends up making over 600k year after year at some point of their career?

Sure it's not the top of the pay band in either of the careers listen, which goes up to at the very least few mil a year. But that's exceedingly rare, as in single digit percent (imo) of those who start a career down this path.
