One of the best YouTube channels for shipping information talks about the Jones Act and the current waiver.

I've seen this topic discussed here quite often. And this video seems to be a great source of information on how the Jones Act works, as well as why we have not noticed any benefit by the current waiver being applied. It's lengthy, but worth it for people who wish to understand the topic completely.

In addition to the video being a great source of information, for the most part, the comments section has thoughtful discussion and additional information.

I'm sure the Mods will remove this if it is too off topic.
