Yeah ok that just plain isn't true. I worked at Goldman Sachs in FIG investment banking, and now at McKinsey and Co in New York as a consultant. While we do have a graphics department that we can call on to help spruce things up, as well as workers in India to help with tasks such as following simple instructions to translate spreadsheets into charts, 95% of the work is done by the bankers/consultants themselves (i.e., me).

In fact, the reason I left Goldman is because as an analyst 80% of your time is spent line editing charts, checking footnotes, and making sure everything is aligned. We even used MS Word with built in macros because Power Point wasn't precise enough. When you're working 110 hrs/week, that's not fun. McKinsey is better but not much different - which is why I'm moving back to SF in 4 weeks to be an entrepreneur.

Same goes for the "I'll hand you over to my colleague" statement. Often times an Engagement Manager who is well versed in the overall project presents for continuity sake (so the audience doesn't get confused by 5 people all chiming in), and questions are directed to the analyst in charge of the section.
