Capitalism needs to be fundamentally reformed or replaced

Following up on this post, I'm now reading the book People Get Ready. A brief, edited excerpt follows:

"In our view, the evidence points in one direction: the economy needs to be fundamentally reformed, if not replaced. Capitalism as we know it is the wrong economic system for the material world that is emerging. [...] But researching this book, what is striking to us is that many, perhaps most, of the people who have studied these matters [...] recognize that if the system is left alone, it will not right itself. Instead, structural changes are needed, and government will have to play the central role in determining and instituting these changes" (113-14).
