The DACA migrants are already here. OK, normalize them but we get the Wall. The point of the Wall is to prevent future DACA problems.
Gee, yesterday 400 "migrants" with children tunneled under the fencing and got their feet on American soil. Face it, once they touch American soil they are here forever. I NEVER hear of any of these invaders being expelled or turned back. They are always PROCESSED, and that means here forever.
Normalizing DACA is painful short term medicine for the greater gain of a sealed border.
What is the ideal immigrant, from an economic perspective?
Healthy young adults, who are educated/skilled/high IQ, fluent in English, and affluent (but at least self sufficient), free of any criminal or drug abuse tendencies, and loyal to the USA.
DACA is a rich pool of recruits for such quality immigrants, already largely settled and integrated, and down the path toward assimilation.
If we go to a quality-based immigration system, skimming the cream from the DACA population, (deporting those below standards), and H-series visas for skilled workers would make up the bulk of our annual legal immigration quotas.
