How do you explain that in other countries this works? Garbage is dumped by humans, it's not a natural catastrophe. All those policies and cultural values you are mentioning converge to the fact that outside Taipei there are huge dumpsters, while in other countries there are not. Why there are in Taipei, it's not for me to judge, you probably know much better the situation. But the reality is, again, in other countries these dumpsters are not there. You can accept the fact, like the culture you mention seems to do, or try to move something in your (perceived) right direction. Either way, I'm definitely not the cause why there are dumpsters outside Taipei.
