I very much like Summers recent focus on tax evasion --it is in the TRILLIONS, and the "Public good" service that is incorporated in every corporate charter, but that has been reduced to simply "serve stockholder wealth". It points toward a needed reform of corporate charters, especially where the public and employee stakeholders interests are also "at stake". I suspect, in the long run, that corporate charter reform will be more important than anti-trust mechanisms in the era where ability to scale is as vital to abundance, as competition is alleged to be for innovation.
If business leaders are serious about doing good, they can start by paying their taxes
