According to what I've read trade deals have cost US jobs, even if automation is a much larger cause. Besides that, trade deals like the TPP give more power to multinational corporations to override what little democracy we have left. That's mainly what they're about.

I do agree that we have to look at the effects of automation and find ways to compensate for the loss of jobs it is causing. I don't think increased job training is going to do it, although we don't seem willing to pay for it anyway. I would like to see a guaranteed annual minimum income tried. It has been discussed since the 1960s. We simply don't need as many workers as we used to. 

Right now the profits from increased productivity via automation are going to the top one percent. Some of that needs to be channeled downward to the people who need it the most. Automating work is a good thing, but it needs to benefit all of us not just a few who own the factories.
