The last clause is important - high investment is a good thing, but if much of this investment is financed by borrowing from foreigners rather than by our own saving, there could be trouble spots down the road. Whether there will be such trouble spots, I don't know. That is another issue I'd like to discuss.
National saving As important as I think it is, national saving has always been relegated to the B list of economic measures. When economic data are released, there is always a great deal of attention to overall output, unemployment, inflation, interest rates, and budget and trade deficits.
