But I do wish there were less illegal people, absolutely.
There have always been pros and cons.
I would say: America (and the "advanced" / industrialized world) bear significant responsibility for mass migration (climate change, economic destabilization, displacement, rapidly changing paradigms, colonization, exploitation, etc).
America also has a history of DARVO when it comes to immigrants (and "unwilling immigrants") , so…
It is what it is.
