China's building up its own society, away from the rest of the world, for a while. Pissing/spitting/picking nose/smoking/loud talking anywhere and staring/asking personal questions/singling out outsiders are social standards. Areas in China are often isolated socially, and whatever the locals do, eat or say is, to them, preceived as the way the world is. Chinese education doesn't challenge the country's social issues for the leadership fears of repercussions. In any case, have a close look at who travels out of China, and then see the problem; those travellers often are the richer and "better educated" Chinese who have what it takes to spread their seeds of social etiquete around the globe. The fact is that it still isn't easy for a regular Chinese to get a passport, and then a visa to Australia, Britain or the US; moreover it isn't troublesome to generate so much cash out of the local salaries either. To change all this, we'd have to send Chinese back to their 1960s-1970s, and then ask Teng Xiao Ping for some assurances (on the paper) that when the borders open, it will really have to be a two-way exchange.
