I choose to interpret what they're saying as something other than this. I don't think they're saying it makes the world go round, I'm hearing that the hunger for more money/material acquisitions (aka greed) is what made them do things to feed that hunger -- aka, acquire or make more money/material goods. That's not necessarily the same thing as making the world go round, although it's a large part of it.
I've always said that I enjoy being frustrated, because frustration is what makes the world go round. Frustration with the status quo -- politically, financially, socially, whateverally -- be it yours or someone else's, depending on how self-interested you are, but it's frustration. Yeah, sometimes the desire to make money ends up badly (as it did with her case), but sometimes it causes investors to invest in good things (as with -- hopefully -- at least some of Wayne's clients).
