There's no shortage of industrial and traffic accident videos coming out of China, very often showcasing horrendous working conditions and absolutely depraved levels of apathy from onlookers, which is to say that China isn't very good at suppressing videos that make them look bad. But in all of these videos, China looks 1000x more clean than India. Am I to believe that the Chinese government cares more about suppressing videos that show litter on the streets than a video of a woman slowly running over a child, putting her car in reverse and running over them again, all while people walk by and pretend they don't see it happen?
The lack of help from bystanders is/was due to some strange liability doctrine that assisting can/could make you liable for damages. This is fairly old information though so hopefully it has changed.
Industrial accidents happen in the US too, although I don't know what rate vs China. I think the fact that their factories have surveillance at all shows they are taking action to improve safety. You've got to consider, the population is 1.4bn, so there is going to be more freak accidents caught on camera.
> China isn't very good at suppressing videos that make them look bad
they are extremely good at suppressing such videos internally
they will sometimes allow something like the particular video you mention (I was living in China when that video went viral, this was about 10 years ago) because it directs anger at individuals' bad behavior, not at the government (in fact, in favors the government making and enforcing rules to disallow bad citizen behavior)
