I don't suppose this "professor" (did he ever hold a job in the real world?) offered any proof of this that you would like to share with us? Hopefully you took notes.
Now calculate the numbers of Americans and Europeans and their average wages vs all the third worlders (China and India alone have 2.3 billion) and see what that means.
Why don't you do this and tell us what it means. Please show your work.
While the third worlders rise up, we collapse
Can you offer any proof of this other than links to the AFL-CIO, Public Citizen or CPUSA?
Thus, killing the middle class..
Again, anything to offer as proof that free trade is killing the middle class? Or, should we all just take your word for this?
Easy, I did do it with a simple comparison of China and the US (go to the CIA World Factbook and look up the median salary of both, multiply it by the working population (all listed for you) and average the two sums togather, then figure out what the difference is)
The results is that China's salaries rise 2.3 times while US salaries collapse by 70%.
