Have McKinsey and its consulting rivals got too big?

Of course they got too big, and especially they got too enmeshed with the auditing business.

It's time to break them all up. The "firewall" that should be there from a legal perspective is a joke in practice, and when there are only three to four companies, there is no place for fresh blood and with it fresh ideas to enter the market.

McKinsey isn’t in the auditing business at all. And those that do play both went the other way, transitioning from auditing into consulting.

There’s a ton of competition in consulting in general.

This is false, the Big 4 are all in the auditing business, in addition to high-end management consulting.
