The authors have a liberal bias and they clearly don't like Trump. If you can overlook that, this is a decent summary of political events regarding US immigration policy in the Trump administration.
The authors provide stories of poor illegal immigrants, but no stories of the US citizens harmed by illegal immigration. The authors don't seem to realize that President Trump is struggling, against many factions, to prevent the US from becoming a third world nation. The reason third world people pay thousands of dollars to cartels to smuggle them into this country is because they can't stand being around other third world people. You can spin it by saying they are escaping high rates of crime, poverty, unemployment, gangs, pollution and inflation, but ultimately, it is other people like themselves who created those conditions. To explain feelings of people who support Trump, Arlie Hochschild wrote, "(Imagine) you are patiently standing in the middle of a long line stretching toward the horizon, where the American Dream awaits. But as you wait, you see people cutting in line ahead of you... many are beneficiaries of affirmative action... Then you see immigrants, Mexicans, Somalis, the Syrian refugees yet to come. As you wait in this unmoving line, you're being asked to feel sorry for them all. You have a good heart. but who is deciding who you should feel compassion for? Then you see President Barack Hussein Obama waving the line-cutters forward. He's on their side. In fact, isn't he a line-cutter too? How did this fatherless black guy pay for Harvard? As you wait Obama is using hte money in your pocket to help the line cutters. He and his liberal backers have removed the shame from taking. the government has become an instrument for redistributing your money to the undeserving. It's not you government anymore; it's theirs."
