Has nothing to do with "benevolence." Most politicians are trying to do what fits what their view of right looks like...whether it is objectively so or not is besides the point. Being the uber cynic like you clearly are is a waste of time and it's intellectually lazy. It allows you to do the whole, they all suck, and move on without any deeper thought or examination.
Recognizing instead that most are trying for the most part to do what they think is the right answer, allows you to then actually look at policies and proposals at face value and ask, will this work, for whom? Whether you are left, right, or middle.
People violate the law all of the time. Do you ever speed? Jaywalk? Breaking the law is not some black/white construct. An infant can't even break the law first of all, they don't have the mens rea and they can't control that they were brought over some imaginary line. And determining if someone "broke the law" is only half the equation, the next step is, what do you do about it...and the answer for 11 million people, the vast majority of whom have not committed any crimes while here, who often pay into the system more than they get out and who greatly contribute to our cheap food and construction costs is not...everybody out.
You would venture to say...why don't you research it first? People are out there who have done the work for you...the Google would help. I think you will find the OVERALL benefits from having illegals with you are a lot larger than you think, and the OVERALL negatives are a lot smaller than you think.
Does that mean it's a simple problem? No. Would construction costs rise so much with Americans at minimum wage or higher that it would cancel out the increase in available jobs and the wages they would pay? I honestly don't know. maybe, maybe not. Would that affect new homes starts? New home prices?
What about food? Would that mean more jobs for Americans picking strawberries? Or would it mean more modernization? Would the increased food prices hurt the poor? Again, pretty complicated question. Yes?
