I wouldn't necessarily put it that way. The top tier business schools teach a good amount of universally applicable soft skills like negotiation, conflict resolution/deescalation, performance management, etc. You just need to enroll. And those skills are applicable regardless of where you go. Having seen friends go through business school, the real value is without a question the network you build during those two years. That's also applicable regardless of where you go. I personally applaud Harvard's new combined major, especially because it supports the thesis that business leaders should also pay more dues than they currently do as technical practitioners.
