Sources for what? The $13/ton labor cost? The amount a retiree pays for healthcare out of their own pocket?
Here is the source for the $13/ton: Trade rules must be enforced
Since I am a steel industry retiree, I think I know a little about the healthcare figures...oh wait...I'm one of those you'd have starve or die...
Sorry to disappoint you, but I plan on staying alive thanks. BTW, I worked in a mill for 30 years...got two BS degrees while I was there and right now I'm three credit hours away from my MBA. I think I know a little more about the steel industry than you do...
