Your post is balanced on a tower of incorrect unstated assumptions.
He basically says that being able to move products and goods without taxation caused this scenario where labour can be sent over-seas to a country with lower wages. This generally means that either that country has all the jobs or other countries have to lower their wages to stay competitive.
There is no mythical place with the cheapest labor prices and an infinite supply of labor. When an employer enters a new country and wants to hire people, they have to increase the wage they offer those workers in the market in order to compete. Those workers actually benefit by doing this.
This also reflects the quality of products and services, since you are paying substandard wages
Sub-what-standard wages? Where does the "standard" wage come from?
and basically taking people who need money to survive
Everyone needs money to survive.
and not people who work because they enjoy it.
Rare breed, they.
On the flip side, the middle class in the more prosperous nations are left without the jobs they'd need to get by,
Oh, are they? They couldn't possibly think up new, better, more enjoyable jobs could they?
or they'd take sub-standard (for their country) wages and scrape along the bottom.
I am missing the assumption that you are apparently stuck on that there is some kind feeding trough of jobs that people, like cattle, line up for...?
Apparently you are also missing the very obvious fact that consumers who buy goods actually benefit because the goods are cheaper.
It's like a broken record with you protectionists. Chinese jobs are bad! US jobs are good! If local jobs are better than foreign jobs, it seems somewhat arbitrary that you choose nations as your granularity. Why not states? Are Arkansas jobs worse than Texas jobs? What about California jobs versus Idaho jobs? Those labor markets have radically different wage profiles--is "exploiting" cheap labor in Detroit bad for the expensive labor market in California? Why stop there? Why not get upset that *any* jobs exist outside your town? Or your family?
Hey, don't buy that hammer, my brother makes hammers!?
