professor klaus schwab greets presidents and rock stars, but as we tried to catch up with him, schwabon't matter at his forum. >> you have to send your ego home, and you re-find it when you come back. >> but not here. >> not here. not here. >> after 40 years, schwab is still the head of the nonprofit foundation that stages the forum. your office is behind the xerox machine and a coffee maker. >> exactly. like we are very tight. >> his forum works like nothing else in part because it isn't formal or official. it turns out people who can't be seen together in public can meet here. in 1989, north and south korea spoke for the first time at davos. when the berlin wall fell, german unity started at davos. and in 1992, mandela and de klerk began the conversation that ended apartheid. queen rania of jordan told us that warring factions in the middle east meet here when no world power can push them together. an arab and an israeli could run into each other in the hallway in this hotel. >> absolutely. absolutely. and not feel they have to pander to, you know, media or to the-- or to be politic
