Buying Bonds

I'm your typical English Teacher in a foreign country with student loans to pay. I realize that the world is in a mess right particularly the US. In spite of that, the Asian economies are still buying U.S. Treasuries. That portends good news and bad news for people like me.
One, it is bad. I've been following the exchange rate and I've noticed that every time there is a bailout, the currency I get paid in is devalued against the dollar. So, the money I must send home is far less than prior to the bailout.
Two, it is good news. If the Asian economies were not buying U.S. Treasuries and decided that they would be independent from the west--well, then, what would be the demand for English (in the long run)?
