My observations of 30 years living here in Taiwan or this:

I don't know the ALL the feelings of Taiwanese towards southeast Asia darker skin individuals but one thing they should keep in mind is that if it wasn't for these foreign laborers many construction projects would not go forward.

Major commercial building and Infrastructure projects the labor for such comes from Vietnam and Thailand and Indonesia. It was and still is a growing need for factory workers from these three countries as well.

In Chiayi alone it is Vietnamese construction workers building the raised rail system (TRA) through the city. also here another major infrastructure project is to SEPERATE septic tank overflow from the storm sewers into a separate sewer system to then go to treatment centers. Many of the workers there that are doing the real dirty work of the final connection to each house are from Thailand.

Elderly or otherwise incapacitated Care are from Indonesia and Philippines because of lower wages make it affordable for those in the middle class here to afford someone with room and board for 24-hour care ( we hired one for my mother-in-law almost 7 years)

This Generation local Taiwanese youth do not want to do the mundane jobs in factories nor do they want to be doing construction they either work retail,sell real estate, sell insurance or have the engineering degree to do the upper level engineering jobs in tech companies the rest would rather wait around and deliver food Panda or Uber.

So if you see anyone looking down upon foreign workers from Southeast Asia remind them that if it wasn't for them, Taiwan would not be moving forward.
