Zeihan may be overstating the significance of some of China's pending potential issues. Nonetheless, their exploding growth and central planning will only work for so long before rifts begin to form along socioeconomic and cultural lines. Everyone is happy as long as prosperity continues but a severe contraction will expose their lack of social infrastructure to deal with unemployment and inflation. As pointed out, they've severely overspent on housing and development. I would add military expenditures to that. They've built hundreds of ships and planes in the last decade to expand their military footprint. When these items begin to age and require huge sums to maintain and operate, reality will set in. They'll most potentially become another a hollowed-out paper tiger of neglect and corruption as Russia's has become.
