OK, I'm not sure if Maslow is 100% correct. Philosophy might not be the pinacle of human endeavor, no matter what philosophers may believe. Whatever the case, people's demands change as they get richer. Engel's law (note the apostrophe - he wasn't a famous friend of Marx) states that the relative demand for food decreases with income.
Virtually no-one in China dies from malnutrition. Cancer is now the leading cause of death. People now care more about pollution than economic growth at all costs. Corruption isn't a big deal if the land reforms by the corrupt official stopped you from starving, but that changes when you aren't so hungry anymore.
And as people get richer, and society gets more diverse, it deepens conflicting interests. Do you want universal healthcare for the uninsured, or a larger private health sector? Should poor people be allowed to migrate to cities? Is corrupt and inefficient public better than greedy private solutions? Not everyone is going to be happy.
And sometimes people just want the right to have their say.
China doesn't want to go down the same path as Russia - a decade of lost growth, then a bunch of thugs taking over the government and industry. But they do want reforms.
Just my 2 cents.
reporter: 你幸福吗？ (ni xingfu ma? or "are you happy?")
migrant worker: 不，我姓曾。 (bu, wo xing zeng. or "my name is zeng").
It plays on a pun of two words that are pronounced "xing," with different tones. The idea is that the migrant worker might have purposely misunderstood the question to avoid answering it with a negative that would have made someone angry.
