Cash Flows

The average American has an income of about $40,000 a year and has, as we have seen, a personal savings rate of zero. The average Chinese earns around $1,500 per year but has personal savings of 23 percent of his income — and is lending a large chunk of these savings, via the People's Bank of China, to the average American.
