Sure, but not always in the way you'd presume. In many instances, management consultants are tools leadership uses to support their agendas, not necessarily to spur growth. I can speak for family-owned European companies (which there are many of and quite big) that operate more conservatively. Despite seeming to "throw money away" at consultants, they continue to do so. So clearly there is market for hiring expensive management consultants. In most parts of Europe, management consulting is seen as more prestigious and better paying than tech or finance, reinforcing the industry's perception of these firms as the 'elite'.

I think all people who are actually building something knows that they bring nothing of value especially when you weight the opportunity costs, but that does not really matter.
