I'm not sure where you got these numbers from but I think you're off by over a magnitude. Taiwan's GDP per capita is over US$30K nominal, and over US$70K PPP. In GDP per capita PPP they're sitting around 13th in the world as of 2023. The minimum wage is over US$800 per month. Trading Economics shows manufacturing average salary of over US$1600 per month. You might have looked at monthly numbers thinking they're yearly. Although even that's low given that the lower bound is lower than minimum wage.
