Honestly, I can't answer your question directly.
In my view, as a member of the Economic Growth Advisory Council, McKinsey acted on a volunteer basis. So I personally don't see a connection between its contribution to the council and its business activities. It's normal for a consulting firm to do business, whether it's McKinsey, the Boston Consulting Group, Deloitte or others... As far as I'm concerned, I don't see the connection.
