Perhaps. But I'm not convinced this new law would have any effect on the scenario you describe. Money is getting pretty good at crossing borders, and the people this mostly effects are not those in the position to put a dent in the trade deficit.
The individuals could be working for large multi-national corporations and still be employees affected by this problem. It's not a sole deciding factor, but if it just adds a little friction in some business options (e.g. hey, who do we have whose willing to go overseas for a year and setup our foreign office) vs others, then it can still affect the needle.
