Personally, I have a sufficient supply of cheap Chinese made junk to last me for a while.
Unlike oil or food, where a supply interruption is instantly felt, an implosion in China will not be badly felt before other suppliers have had a chance to ramp up
I think the main problem with a Chinese implosion is that they will be forced to sell their US Government bonds, which means our government wont be able to find anyone to finance its deficit spending.
