My wife is writing a paper on how regulations hurt U.S. businesses when competing with their oversease counterparts. The instructor wants her to be more specific, so what would be a good aspect of harmful regulations on which to focus? Think in terms of environmental regulations, labor laws, etc. What should she focus on while at the same time using sources that aren't overtly libertarian? He specifically warned her to be wary of conservative/libertarian articles with an agenda, and prefers "apolitical," peer-reviewed (i.e. liberal) sources.

I figured that the gold fanatics here would be able to enthusiastically provide some advice.
