Simpler....
Are Mexicans who can spend money haveing any problem crossing our border?
Simpler or different? That seems like an entirely different question than the one you asked before.
Not really I hope to point out that all of the problems you mentioned may be real , but that they are trumped by economic considerations.
Which of these problems do we have with Canada?
Canada has been shareing our economy for generations , they are as wealthy as we are and we scarcely defend our border against Canadians at all.
Canadians who cross the border to work are unremarkable and can land almost any job an American can, after all they almost speak the same language.
Economics and language , I think we could modify the circumstances of economics and language and gradually decrease the pressure that makes the Mexican border so contentious.
We have had at times as much as 15% of Mexicos workforce on our soil , earning cash and learning english.
Why are we not useing this as an oppurtunity to spread our message?
WE should not only make it easy to cross the border for the purpose of honest work , we should make education availible to the Mexicans and other Latinos we therby find availible to our indoctrination.
Byt he time that they return to the land that they love , where they have their familys , they would not only have a pocket full of cash , but they would have a working knoledge of English and an understanding of American style good government.
WE could gradually do to Mexico what we have done to Canada and improve them into good neighbors who absolutely share our economy and remain seaprate for the sake of nationalism alone.
