Simply because as a matter of fact China still has plenty of rural surplus laborers and people are talking about a magnitude of more than 200 million - so you know from national-wide point of view, there is plenty of labor supply there.
Given the evidence of deteriorating investment efficiency, China needs to rebalance its growth by shifting away from investment toward consumption.
There's only one conclusion: Continuing to bolster labor-intensive production and exports is the only viable means for China to absorb its surplus labor and improve rural living standards.
You could say China is actually 20 percent richer than anybody initially thought.
It's a challenging task but that shouldn't be an excuse for China not starting on it right now.
