—too much emphasis on spending money on innovation and technology. I think that kind of continual change is what leads to unproductive results. There's a lot of expenses involved in that: staff turnover, training, time, money, hardware. That's what's taking away from productivity.
There is another thing I wanted to say that I didn't really get to say too much about before. I think there's a real danger if we don't do something to stop the emissions of carbon dioxide and greenhouse gases. Once the effects start to occur it will seriously impact the economy in a negative way. So doing something about that is also part of being productive in the economy. We have to stop emitting carbon dioxide.
