This sounds like a good thing. If we had more laws like this, we likely wouldn't be in the current situation where national security is threatened by squabbles between China and Taiwan.
Nah, Congress keeps shipbuilding alive like any other too big to fail shit show, making the navy buy and maintain ships they don't want and at exorbitant costs because the ships are flawed from day 1.
All the Jones Act has done is increase shipping costs in the country as every shipper is forced to use trucks and rail freight instead. It impacts everything, even the costs to build homes because heavy bulk goods more or less end up on trucks over long distances.
