Regarding Mr. Knight's comparing Poland and the UK with America and Mexico.

I would like to provide a little light for Mr. Knight.
First, it's a simple walk to cross the Mexican border into America whereas it's a very long walk from Poland to the UK. Also the Mexican government encourages migration, legal or illegal, into America, so that the cost of social responsibilities are shifted from Mexico to American taxpayers. Also the money earned by migrants in America is returned to their families remaining in Mexico which also reduces the government's responsibilities.

And a bit of irony, the Mexican government does not hesitate to immediately remove any illegals entering Mexico from Central America. No benefits, no schooling, no healthcare, no jobs, no nothing!

A job void has been created in America due to the movement of people not willing to work unless they can obtain the better paying jobs in construction and leaving open the very hard work in the seasonal agricultural fields that pay much less.

I find it amusing that Mr. Knight, living in the Northeast, Boston, has such a remarkable application of the Mexican "problem". We in Arizona, where it has been happening for decades, can only guess it is a part of the very liberal mindset of social engineering elitists.
