China famously (among economists) has the highest national savings rate in the world - about 40-50% of GDP, compared to 10-15% for the US, 20% for Europe, and 25% for Japan. China has very different cultural expectations related to saving and spending. On the other hand, the US spends a higher percentage of GDP on education than most countries, which is a different form of investment in the future.
