Children losing fingers or hands while being forced to work 14-hour days in horrible conditions. Slave labor in Burma, where dissenters are reportedly tortured or murdered. No one supports child labor, and no one supports forced labor. Of course we should not import products made this way, but we should go beyond that. We should do everything in our power to try to stop these practices.
Similar stories exist with the environment.
If we did not ban trade in elephant tusks, elephants would become extinct. It's that simple. Our economy also loses if other countries lower their environmental standards to undersell American companies. Our workers lose if foreign companies unfairly lower labor costs by using child labor or forced labor, or by refusing to give their workers a voice. These are also not new issues.
