You have no idea of the horrendous conditions that many "illegal" migrants are fleeing.  Mexico, for instance, is closer to a failed state than anything in this hemisphere, and parts of it are run by drug-funded warlords, much like Afghanistan or Somalia, which ARE failed states.

Given that NAFTA and the War on Drugs contributed directly to the crisis, the USA is obligated to aid these refugees in ways that our denial of history make ambiguous and unclear.

DACA is what immigration policies look like when you refuse to acknowledge that American action has created an immigration crisis, when you pretend that history doesn't matter. With that said, the amount of pain inflicted by repealing DACA will in no way be balanced by any good that it will do.

The repeal of DACA is red meat to the xenophobic white nationalists who elected Trump. The repeal of DACA will do NOTHING to make the US safer or more prosperous.
