What makes you think those places will still be more polluted than the US by that time?
There's this magic assumption on your part that the current state remains unchanged.
No. But YOU have not explained WHO would clean up the YEARS of pollution or WHY they would do so.
Greece is first world too.
Yes, as I have specifically pointed out to you.
Those Greek workers aren't pursuing opportunities in Greece. They are actually chasing opportunities in the developed world.
Again, as I have specifically pointed out to you.
You are restating the points that I have made while ignoring your own claims.
If the EU ceases to be developed world,
HOW would that happen?
Also Greece isn't an unusual case of a first world country with net emigration. The article mentions Ireland, Spain, and Portugal as well.
And, again, it is the WORKERS who are pursuing jobs in other 1st world countries.
It is NOT the OWNERS OF THE COMPANIES moving to the 3rd world. The OWNERS OF THE COMPANIES are moving the manufacturing jobs to the 3rd world while they keep their families in the 1st world.
You seem to have a problem understanding the difference between a WORKER and a person who OWNS THE COMPANY.
