Obama justifies this executive order by saying that these young illegals will make "significant contributions to society" and that "it's right."
Well what about all those young people who come here legally? I have personal friends who legally came here while under sixteen who'll get deported if they can't find H1 visa sponsors (which aren't cheap). What about them? Are you simply going to toss them work visas too? What about international university students who must return to their home after they graduate, whom we know are trained with skills we could use. Are they also going to get free visas simply "because its right?"
Are you honestly penalizing them by rewarding those who broke the law to get here? President Obama, are you honestly going to look at true contributing aliens in the eye and say "too bad about your visa, your first mistake was come here legally?" As far as I'm concerned, illegal is illegal. You can't pick and choose by executive order which is which.
You think a constitutional lawyer would know this.
