From what I understand, free trade allows for unparalleled wealth creation by optimizing the flow and utilization of capital, which is fantastic! The problem is that it optimizes other things too, like labor costs by taking advantage of countries with incredibly low minimum wages, workplace safety standards, and standards of living. Meanwhile, the increased profit doesn't go to the society impacted by the transfer of these jobs, but rather to the capital owners, thus exacerbating wealth inequality. So yes, free trade does create more wealth than non-free trade, but it's not to the benefit of the society losing the jobs.
