Let me guess, you or someone you know is a plumber or has a construction business. You were used to over charging your customers for everything and getting away with it, which meant you didn't have to work much, and were probably doing a crappy job anyway because you claimed white privilege. Then one of your customers bailed on you because a Mexican guy did the work for half the cost, or less, and did a much better job. In fact, that Mexican guy was not actually illegal, but because he was Mexican you called him illegal. Anyway, that started happening more and more and now you (or the person you know) has to actually work to support his family. But, because you're a racist, it's easier just to blame someone else.
The truth is that an illegal alien did nothing to you, ever. Maybe the kid of who you call an illegal took your kid's spot on the soccer team, and was better and worked harder than your kid, and as it turns out that kid speaks multiple languages and has a brighter future than your kid ever will. But it's easier to blame "illegals" for ruining our country. You know what, you really are a racist.
