If it matters to you I hope you are right. Personally I'm unconvinced. Note in the video he specifically points out the Ti hubs hell which is absent on the hubs I'm questioning. That feature is one reason I use White hubs more than the made in the usa thing.
If they really do make the lower end hubs they should change their website language to say "made in the usa" instead of "designed in the usa" because designed is exactly what one would say if it wasn't actually made here.
