Once again you shown no understanding of what free trade is or means. Does it mean that no one loses a job? NO of course not. It does mean that someone pays a lower price for a product or service? Yes, it does. Does it raise employment and wages in both countries? WHY YES, it does.
Construction is almost totally independent of international trade, so is food service, nursing and hospitality. Agriculture could be affected but is MUCH more affected by tariffs against imported commodities i.e. anti-free trade laws.
It seems clear that you prefer an Iron Curtain to freedom. What do you think “free trade” is? You are apparently totally confused as to what it is.
Why don’t you explain what the Doha round is and how it affects “free trade”.
Explain how an open border and illegal immigration is crucial to “free trade”
Then explain why and how our food import standards were ‘haromonized’ with countries of much lower sanitation standards and how it relates to “free trade”.
When you do that, I’ll believe you have some inkling about what “free trade” is.
