I think your numbers match what my cousin shared. In both my conversations with my cousin and in the reddit post, it is unclear if reported salaries are take-home or don't include the OT and bonuses, but I don't get your point?

My point is: Engineers in Taiwan work more hours because they are paid to work more hours (OT). Engineers in the USA are not paid more if they work 35 hours or 60 hours.

If TSMC wants to address the culture gap (get the Americans to work more), TSMC should pay up.
