No offense, but can we lose the "Dreamer" term already?  It's euphemistic BS designed to elicit tears.  Their freeloading parents are at fault, but they don't deserve a soft-teddy bear euphemism to make me cry in my soup.

That said, just sending them back on a train with nothing probably won't work.  I imagine if somebody threw me on a one-way plane to Austria, where my grandparents came from, with a second-rate bilingual US high school education?  I'd be screwed.  If you want to send them back, it can't be empty handed.  Maybe you should have removed their parents when you had a chance, congress?  Liked the slave labor too much?  Well now you have generation 2 and 3, considering these people have their own children now, which are somehow citizens, due to a flawed interpretation of birthright citizenship.  Good luck sending them back now when they have their 4-5 babies that are "citizens".  Maybe you should work on figuring out a way to stop this, and prevent it in the future?
