100% agree with the above.
This deserves more attention.
I'll tell you exactly how we feel about it. My family was fortunate enough to be granted asylum by the United States for persecution we faced in the Middle East. Luckily, we got out relatively unscathed. One of my uncles, on the other hand, was not so lucky. Despite years of trying to immigrate legally to the United States, no progress was being made for him or his family. Why? Because it's an insanely difficult and expensive process to legally enter the United States that requires more than a bit of luck. One day, he was kidnapped off the streets of Baghdad by a terrorist group. For 4 months, he was tortured daily and held for ransom. He had to endure electrocutions, finger nails being ripped off, cigarette burns, etc. Now--thankfully--he's in the United States with his family, but all in all, it took them more than a decade of paperwork, fees, and serious effort on our part here in the US to get their request approved. In high school, I worked at a car wash. The Hispanics I worked with were some of the most hard working individuals I had ever met. They're here in America, and they are happy to clean your filthy car and earn a living wage that lets them support their family. I can tell you that this attitude was not shared by most of the natural US citizens that I also worked with.
The attitudes held by you and select others in this thread are all too common. Quite frankly, you take your US citizenship for granted. You don't understand what it is to grow up in a place where your existence is routinely threatened, whether it be by ruthless organizations like ISIS or by crushing poverty that you simply cannot fight against. Knowing what I know, and having seen what I have seen, I totally understand, and sympathize with, immigrants coming here illegally. America is truly the land of opportunity, especially if you're coming from a land of no opportunity, as many of us are.
