Then should have explicitly defined "everybody" as "everybody in the USA/developed countries". The US as a whole isn't being hosed. The USA as a whole benefits from trade with China, but a significant subset of its population is getting hosed because of inequalities in ownership of companies that benefit from the trade. Now if we made sure that every American worker owned shares in those companies, everyone, including workers, would be better off than if there were no trade.
