For example, Jeffrey Knoll wrote in the TLS comments section two months ago:
Another example is from Peter Schiff, who said in a debate four months ago that:
Cato even published a paper (pdf) back in 2003 explaining the challenges that the Chinese pension system faces. And this demographic issue is only going to get worse, or in the words of The Economist — China will become old before they become rich.
Not only has the Chinese government implemented several types of social security plans, but foreigners are fully co-opted into the apparatus too.
In fact, the only way for a foreigner to get out of the new laws that were passed last year are to sign a promissory note, saying that you will never work in China again.
So, just like the myth of a China that is visa-free was busted, the myth of a social security-free China should be taken off the list as well.
Below is a fantastic overview from Matthew Stinson regarding the new laws, specifically applied to foreigners.
