That was my point. Corpos aren't just going to take less margins if labor costs did increase. And my point doesn't even necessarily disagree with what you're saying, because greedy corpos are going to be greedy corpos and will use any excuse to raise costs.

But regardless, my main point was that the economic relationship between Mexico and the US is way more complex than you and the original comment are making it out to be. Unless you're an economic expert specializing in international trade, I'm not going to really take you armchair opinion seriously on what would happen if Mexico suddenly ceased all business with the US.
