Severe poverty in other nations Is another big part for immigration! At the same time, we in the states have a huge shortage of workers. Our workers are aging, and so the answer is that we need immigrants. Let us, in partner with other nations, set up international safe zones, job training centers.
The training would be funded by private companies looking for skilled workers in the future. Once upon passing the training classes, immigrants can be allowed to get job visas into the US.
International safe zones would prevent people being taken advantage of. Great for humanity.
