That's a very good question. In fact, I know that Jayson Myers of the Manufacturers and Exporters has a very interesting chart on that. Up to about 2001, companies were making quite active investments, and generally companies that keep making those investments keep their productivity levels up and are able to deal with foreign competition.
Our productivity levels, by the way, are about 62% above those of the United States, so we're not in a low-productivity business.
Since 2001, because of energy costs and because of the dollar—and we see the dollar has gone through a big change in the last little while, but actually it's been going through this change for above five years—the amount of money available for companies to make those capital investments has gone done. We've even seen it in terms of environmental performance.
