I'm not completely up to speed on DACA, but here's my quick take.
The people that came here illegally decided that America was better than the countries where they were. They also decided that America was better than their other options. They didn't go to Sudan, Bolivia or Zimbabwe, they came to America.
America's goodies are predicated on the rule of law. Without it, we're run by mobs and life is unpredictable. No treats like top universities or good jobs then! So the DACA people came here because the rule of law allowed us to create the things they wanted to consume. Now that they're here, the rule of law is in their way and needs to be suspended. Just for them. Just in this circumstance. Because they say so.
Welcome to the United States of DACA.
