To be more specific, I think it says a lot about the general attitude of people that have grown up under the CCP, and the 'take what you can get or starve' environment they've fostered.

It's seen in other ways like lack of queuing, littering, and the general corruption throughout all levels of bureaucracy.

The attitude is far less pervasive in Taiwan, Hong Kong, Singapore, Malaysia, or other countries with significant Chinese populations.
