Jester,

Indeed - As you say, it may take some time - but eventually, inevitably I think the Yuan at least becomes a large part of the basket that determines world resereve currency, or takes the title outright. I think when that time arrives, it will creates havoc with our markets and our economic strengths (and the 'sins' of our economy that gets a 'pass' from worldwide investors, producers, etc.)  Maybe it happens sooner. Maybe we never see it after full transition. But if you have kids, I don't think it'll be pretty for them. If they're college age, and interested in business and economics,  taking courses in Mandarin might be a good move.
