We've had essentially the same border we've had since what, 1960 or so? In that same amount of time, the wealth of this nation has increased by massive leaps and bounds. We have incredibly high literacy, incredibly high functionality, incredibly high levels of technological achievements, artistic exploits that are world-class, industries that create more revenue than many other nation's entire GDP.
It would seem to me that if the Illegal aliens were sucking out a trillion dollars every decade from the country and contributing nothing; our dominance in the financial, technological, military, and even cultural realms would not have been possible over the past 60 years or so. So I don't think there is much of a crisis on the border.
That being said, if you're here illegally, you should be deported. I would be for giving an illegal alien a place near the front of the line if they have been here for a while, have worked steadily, been on the right side of the law in all other areas, Saying "go to the back of the line" seems silly.
