Is this 8th grade economics? Consider a nation that has strong tariffs on imported goods. Consider another nation that has major obstacles to the investment of foreign capital, and lots of cheap labor. Now consider a political campaign (it doesn't look a campaign, but it is) to remove the tariffs and allow capital to move freely from the first nation to the second.
Result: dramatic changes in the first nation's wages, at least for work that gets moved to the second country.
Remind me again which law(s) of nature is involved here.
