To a degree you are right, but you must know that it is the geriatrics who mostly keep the streets and parks as clean as they are. Muzha is clean along the river and through the uni because old hikers go through the area every day.
The other problem is that Taipei will improve but not the countryside as the level of education out there is very low. Just go out to Taipei County any weekend and the garbage tossers are mostly young families.
What will happen though is that a tipping point will be reached at some point in the next 10 years. The problem now is that there is so much that must be ignored that it is hard to know where to start. People don’t like their old run down buildings but what can they do? No one wants to take the first step. Many are just waiting till the buildings get too old and then they plan to tear them down and rebuild. That’s what my neighbors want. Until then they can’t be bothered to repaint the stairway or fix up the outside.
Many many people desperately want a better Taiwan but don’t know where to put their energy. When some direction is given there will be a lot of positive change to this place. Just look at the fish conservation programs set up by the EPA. They wanted to monitor rivers to help restock the fish populations. They had no problems getting hundreds and hundreds of volunteers around the island to help patrol rivers.
As john said, two steps forward, one back.
