What does Warren Buffet have to lose?

Warren Buffet said,

If we don’t get it [the economic crisis] solved next week, I may have to go back to delivering papers.

He has also made a $5 billion investment in Goldman Sachs and a $3 billion investment in General Electric.

So what does this mean? I don’t know. Does it mean that the ultra rich have a lot more to lose from this economic crisis that the average Joe? What will the average Joe really loose if we let the crisis happen? And what will he gain? I wish I knew.
