Since the "winners" from free trade can more than compensate the "losers" why does it matter if wages and employment fall when a country engages in free trade?

What will be an ideal response?

While it is correct that the "winners" from free trade can more than compensate the "losers," this rarely actually happens. First, the government might not be able to effectively carry out such wealth transfers. Second, it is often difficult to pinpoint exactly who the winners are and how much each gained, and who the losers are and how much each lost. Many people enjoy small benefits from trade but a few people suffer very heavy losses.
