Yes, they are, and that's an ongoing issue of supply. It comes back to the issue we were all discussing earlier about productivity. Unless we can get the output per worker or the output per unit of invested capital up, then, indeed, we have a problem. The first thing that happens is that prices go up. Those prices go up to curb demand, to bring the demand back down in line with this rather weak capacity to produce.
The way forward for us, especially in this difficult period when we have all this change going on, is that we have to increase the share of our national income that we devote to investment to raise that productivity. That's just the very unfortunate fact of life we're in. That means that in the short run we are going to have to give up, collectively, some elements of consumption in order to provide the real resources, both human and physical, that are needed for the investment to raise that productivity over time.
