Sure but that is not the actual trade off. You don't prevent an economic crisis by allowing foreign investment to slow down. To use another medical analogy the idea that you can prevent an economic crisis by slowing growth is like the idea that you can cure diseases by using leeches to suck out them out.

Encouraging American business to move factories outside of China does neither of those things.
