Obviously this shouldn't have happened but let's not jump to conclusions that they're skimping and it's a money thing, I'm not sure we'd jump to the same conclusions at a similar scale Western park.
Doesn't have to be a money thing, could also be an organizatorial thing (company bureaucracy could be a hassle, for instance). A failure of routines. Poor routines to begin with. It could be a one-in-a-milllion occurrence, or likely to happen again tomorrow by coincidence. No place or organization is immune to poor decisions.
And yeah, I agree that there's no need to think it couldn't have happened in the West too. Heck, just have a look at
CF's Accidents page. You have the common "Guy walks where he shouldn't go, gets struck by attraction and dies" thing happening anywhere, but also the occasional "Vital structural part snaps, attraction falls" type of accidents too, or "Engineers ignore an alarm and dispatch a train full of passengers into a valleyed train". I've seen enough examples of bad HSE/OSHA compliance in the building industry over here (which generally tends to be super serious about stuff like that) to know that it could really have happened anywhere.
Areas where a mechanism drops suddenly from the ceiling (or anywhere machinery is prone to sudden movements) should really be locked away. Preferably in its own cage, inside a locked room. Physical barriers, not just warning signs. Maybe a sound alarm too. It apparently wasn't done here, and it wasn't done in that German assembly plant where a car manufacturing robot bludgeoned a guy to death last year. It doesn't mean that German car factories are death traps, or that the specific plant doesn't care about safety. But it means that somewhere, a major screw-up happened, and it could and should have been avoided.
It probably was tactless of me to suggest that negligience extends to the rest of the park, though. I'll give you that.
