If the goal is to reduce market flooding by subsidized Chinese panels, why not just apply tariffs to Chinese imports (like the EU does). Trump's tariffs apply to all imports.

    If you are a big-government type person, as most 
    Trump critics are, this sort of federal level 
    economic shaping should be something you can get 
    behind.

This is a fallacy. Here's a similar one to point it out: "If you are a person who likes rainy weather, the hole in your roof should be something you can get behind."

Specifically, just because someone supports the notion of a large federal government to tackle large problems, does not mean they should support the idea of a large federal government for any arbitrary reason.
