Probably because they aren’t human labor intensive and most of the costs of fabs are in construction and equipment, and almost all of the expensive lithography stuff comes from ASML (a Dutch company)?

The EUV light source comes from ASML which is indeed Dutch. Although the technology (zapping tiny droplets of tin with a laser as they fall through space) was largely invented in the US. It's an extremely complicated and expensive kludge but it works.
