This sounds very optimistic. A more realistic interpretation is that the companies which control governments don't have moral principles and don't pick sides. In the case of weapons manufacturers, they may sometimes back both sides. It may also be profitable for banks to back both sides of a war if they don't currently have much collateral in the affected countries. Providing loans to rebuild countries is a great way to profit from war and establish a presence there.
Big companies like to lobby governments into creating problems for which they have solutions to sell.
I mean just look at what happened with companies like Mercedes Benz and Hugo Boss which were selling tanks and uniforms to the Nazi government... Still very successful today, didn't even change their names. They didn't have any problems finding customers or investors. Clearly it means that nobody who matters economically cared about the war. Quite remarkable when you realize that we're talking about WW2. In the business world, it's as if WW2 didn't happen.
