@Setanta,
I see, thanks. So this practice is applicapable to "high income bracket people" in the US. But workers are usually laid off. Do I understand it correctly?
But in China, this word "buyout" is applied to workers, that is, they are not technically laid off, but they are "bought out," with a little sum of money, and they should never come back again for any benefits. But maybe we should not use "buyout" for the Chinese context." I hope you understand what I am talking about.
