Estimates of total illegal immigrants present is down under Obama. We took in a half million refugees in the previous three years. Did you know that? And that says nothing about other immigration. Most people don't know that. Most people don't even notice. Why? Well, because we are an enormous country, in size, population, and wealth. The influx of children is a relatively SMALL influx. It is straining resources only because those resources are small. No big deal. If you think the world is ending it is because you are listening to the ridiculous hyperbole of the right and you picture a gazillion plague zombies storming the border.
This is a minor problem. It is perfectly solvable. It registers maybe a 1.5 on a scale of 10. Just relax.
So what do I see for the future. I see a group of people saying the same story that has been told since the beginning of time. A group of people of privilege terrified that terrible "others" are going to destroy their way of life. Same story told by Hitler. Same story told about letting women vote, freeing slaves, etc. The story has always been wrong. In part because the privileged over-inflate their importance and in part because they under-value the Other.
These people always lose and eventually fade away. That is our future as well. In fact, I think they have already lost and many are starting to realize it. They still hold the chains, but it is a thing now beyond their control and honestly I think it scares the crap out of them, which is why so many of them are completely unhinged.
