Really? I can't think of a culture/society where people that need to work hard don't do so...even into old age. Even as migrants to America, the first and sometimes second generation bring a strong work ethic with them. I'm sure the Chinese are very hard working...but they're hardly an exception if you look around the world.
You are right, the Chinese in the young generation are not as hard working now. (Maybe I am geting old)
I haven't read the article yet, but I would rather that my trash and recyclables were strictly between me and the processing plant. For one thing, we all throw out paper with loads of exploitable information. Secondly, I am fairly certain the Bay Area sorts its trash after collection, so extracting recyclables earlier in the process isn't really of consequence.
They represent a testament to hard work, even in later life, that few cultures manage to exemplify quite like the Chinese seem to do.
