I give up! You're obviously out of my league and I'm in submission to your knowledge [I leave our conversations feeling like it is
you who is taking credit for having taught
me things]. I'll let you do the critical thinking about the benefits versus costs of what the Chinese do to their own currency. Hint: there are tradeoffs for them. Just as everything in this world...there ain't no such thing as a free lunch. And, since you know what the heck your talking about, I'm sure you can figure it out.
Oh, and when you do figure it out, you can post it and then genuinely take some credit - assuming it's accurate!!!
