This is more correct than people think. Back during the Obama admin, they pushed forward doing a second Reagan era approach of "we'll promise security in exchange for asylum", but the republicans didn't take the bait. They think that we can just do round after round of amnesty once people get uppity, and that will solve the issues. Notice how expedited deportation is at the whim of the executive branch instead of mandatory by law? That's so they can chose not to do it when they want to let people in, then put pressure on keeping those they allowed in to stay.
The bottom line is that this is the consequence of congress' failure to come to an agreeable middle ground on immigration, and instead giving the executive more and more power to implement policies as they see fit, even if it goes against the words and spirit of the actual written law. This is precisely what happens when you try to give all of the power to the executive instead of working it out in congress.
