Well, first of all let's just make clear that it's not like BCG was paying him $16k hush money because his story is amazing.
They pay everyone a $16k bonus on the way out for signing that thing, whether people who have a gripe or others who have only good things to say. It doesn't somehow give him credibility.
Aside from that, there are people who go into consulting and gain a lot of skills, and others who do the least work possible and leave. Some who find great fulfillment in the right corners of the work, some who find it totally dispiriting.
This is just one person's experience, not a salacious tell-all about the "dark underbelly of an industry that no one wants to talk about".
