Belgian and Dutch workers have a domestic shipbuilding industry of note which the US doesn’t really. They have the benefit of many, many decades of expertise so they’re far more productive than some hypothetical US shipbuilding industry. And US workers are paid more in every industry than foreign equivalents in every industry I’m aware of. The US is much richer per capita than every other independent state. It’s worth it to pay those labour costs if they’re far more productive but in this industry they’re really, really not.
