Which leads me to the rebalancing of economies. Unsurprisingly, economists can’t agree about the primary reason China’s domestic consumption is so low and what should be done about it. One possibility is the population’s focus on saving—in large part to cover the cost of health care, education, and preparation for old age. This is exacerbated by China’s massive and rapid urbanization; as it currently stands, most social services, such as education and health care, are administered in one’s home city. This means that much of the migrant workforce can’t access these services in their new cities, and is forced to save to cover those expenses. While local authorities may balk at paying more for social services, there is a trade-off: Addressing such structural barriers would free up workers’ income that could be spent locally, stimulating host cities’ economies.
