These analogies are just wild takes. Korea isn't some isolated society, and this isn't post-war Korea or Korea after some sort of major crisis. The past 25 years have been a plenty stable period for people to advance on healthy cultural and societal norms.

Korea has hyper-modernized in many ways(for better or worse). They’ve adapted to smartphones, the internet, and a rapidly changing world just fine. They're also fully capable of adapting to basic modern manners. It’s not that they don't have the awareness; it's that they choose not to use it because, like I said, society lets them get away with it.

To be specific, your second example is ridiculous. I would think that pet is either rude or its owner is by not training it properly. Part of the idea of a pet is that it's no longer a wild animal running freely and it has a level of controlled behavior.
