Yes, there are a few million undocumented people in the US. How many, who can say. The Pew Research group believes that number was around 14 million in 2023. But, it is impossible to really say. But that doesn't really change the overall argument. The reality is the US economy is greased by the undocumented. Saying otherwise is a lie. If you were to deport all of them, it would have a catastrophic impact on the US economy. We're actually seeing some of that damage right now.
Look, as I said, I do not have the answers here. I understand and believe that fair immigration is important, and undocumented people can be a problem. But, for the most part, they are expanding the US economy, not weighing it down. And, I acknowledge that there are no easy answers. Deporting tears families apart, and the Trump administration is sending refugees back to places where they face persecution, torture and death. But, also giving undocumented a pathway to citizenship also would increase the numbers crossing the border. There is no simple solution, but what ever gets done will hurt both sides (left v right) in one way or the other.
