You raise a good question. Clearly the answer is more trade protectionism by the US, including higher tariffs, quotas and tighter government regulation of our labor markets. After all, free markets simply exploit working families for the benefit of the rich. We need to be careful not to fall for those misleading arguments put forth by mean spirited conservatives that a rising-tide raises all boats and that situations like this are not a question of zero-sum gain.
Furthermore, the unfortunate loss of life by the displaced worker is clear indication that we need more gun control now.
