I'm in the same boat. It's been difficult. I cannot express how grateful I am to Jose Vargas for writing this story. I was brought here as a kid 13 years ago. I'm 24 now. I also graduated from a "top" university -- like that matters. I guess my parents weren't smart enough to get a fake social security card for me back then, I wish they were. I've also been fighting for the Dream Act for what feels like an eternity.…
There's one simple problem with changing immigration, and that's the system is working as intended. Farm workers can't unionize nearly as easily if they are undocumented, and undocumented workers don't have to be paid standard wages. In fact, they can explicitly be paid substandard wages and there is no way to complain. Your parents, most likely.
Undocumented workers lower unskilled work wages and working conditions far past what a documented system would. Further, as workers age out of the ability to do backbreaking farm work, they have no legal protections on which to rely, and can be thrown back out more easily. The DREAM act, however, brings people into the system with legal protections, people who can't easily be exploited in the same way their parents are. Your parents, that is.
And that's why we face an uphill battle with the DREAM act. It sounds conspiratorial, and nobody would explicitly admit this; sometimes, we get to status quo through unintended consequences, but people build their businesses on unintended consequences, and change isn't something they take easily, especially when it impacts their bottom line.
