Explain and discuss the reasoning that might have been used to claim that trade liberalisation with the developing world would ‘[harm] less-skilled workers in developed countries

First, explain and discuss the reasoning that might have been used to claim that trade liberalisation with the developing world would ‘[harm] less-skilled workers in developed countries’ and why this reasoning may not have worked, as preliminarily concluded after the intense debate. (1000 words)In a recent journal article, Prof. Adrian Wood (University of Oxford) stated the following:
“In the 1990s, after an intense debate, the economics profession concluded that increasing trade with developing countries was not substantially harming less-skilled workers in developed countries. Twenty years later, however, it was widely asserted that the costs of globalisation to less-skilled workers were a key cause of Brexit, Trump and political extremism in continental Europe. Did the economics profession thus make a serious mistake?”
