The panel tariffs are a problem because it's possible the negative impact on non-manufacturing (solar installations, etc) will cancel out the benefits from the tariffs :( But yes, there are definitely things the government could have done to protect local manufacturing. I'm still not sure the steel industry could've been saved. At this point I think the real failure is that the government didn't do enough to help people trapped in dying rust belt cities. Unions can't bear the blame for that.
