1) Chinese expansion will continue after Western Collapse. Your theory is totally flawed. Did the USA stop production after Europe destroyed itself in WW1 or WW2? The opposite was true. China's power started by an influx of foreign revenues to get the capital (tools and expertise) they need to build themselves up. But ironically, the state controlled economy is more effective and recession proof than the US one because they have direct command and control over their corporations and resources. Meaning, psychological bullshit like stock market crashes won't pop the market as it would in S.Korea or USA because they can simply mandate many thigns that we can't. China's goal for perhaps the last 10 years, has been developing an interrnal market in order to shield themselves from the outside world. This has been evident in everything they do and part of the reason, they've kept the yuan devalued (so their citizens, HAVE to buy domestically made products).
2) If you actually think outsourced production centers are going to move to Africa or the Carribean, you've gone made. It's not about cheapest workforce, it's about cheapest manageable and reasonably intelligent work force. Put the big 'racist' stamp on me if you read into that to much, but Haiti's trade relationship with the USA is nearly 300 years old...there is a reason why we didn't outsource there like we did to China. Use your head. If we'd go anywhere, it'd prolly be Central Asia, but then their land-loccked environment would make it much more difficult and expensive.
