Trump also feels that there’d be a dramatic effect on society if we deport DACA recipients. He feels that ‘real’ Americans will finally get their country back. He has an image of what America should be. It’s what it used to look like, and he’s not emotionally comfortable with what it looks like now. That means language, culture, physical appearance, etc. Based on his reactions to the incidents in Charlottesville, I think he’s more concerned about that than actual crime or employment statistics.
Most people feel that America is changing, and most people have a problem with it. Those who don’t say that are probably coping with it better than others. Now, that’s probably a slight majority, but most take issue with it. However, many people confront their own insecurities and don’t allow them to affect their decisions about who to vote for, who to hire, and if they’re an official, how to write and/or enforce policies. Therefore, it’s all about how we handle the situation.
Trump has also said the government will be better off, claiming they won’t have to spend as much money on deporting illegal immigrants once they’re all gone. He could also just not spend the money deporting them in the first place, and that would cut the cost right away. Therefore, yet again, he’s showing that cost is not really his motivation here.
On the other hand, I do think the government would save money and actually make money. The government would get more withholding tax because workers would be paid at least closer to the minimum wage than before, and fewer would be paid under the table with no tax record at all. It’s clear that none of this is the reason why Trump wants to kick them out, but I do think the government would make more money from payroll taxes.
The government would, of course lose billions because productivity would drop, which leads to a drop in tax revenue because taxes paid on income drop when income drops. Of course. When lower productivity causes companies to have less money to pay their employees, whether they’re working there illegally or not, those workers will have to be laid off anyway, which lowers payroll tax. Don’t forget all the sales tax losses, as well, because people won’t be spending as much because they won’t have it. Since the money won’t be spent and, in most cases, since we don’t have a wealth tax in the United States, money not spent is money not taxed. So when things slow down, no matter how that happens, the government loses tax revenue from that.
