As a legal alien, I welcome the idea of cracking down on illegal immigrants. At the same time, I’ve seen many businesses in the U.S. run sweatshops and profit off desperate people willing to work for trinkets.<p>Asylum seekers are another huge problem. I personally know several distant relatives who are illegally seeking asylum in the U.S., Germany, Italy, and France. This is unfortunate for those who genuinely need these permits. But at the same time, cracking down on this is paramount to reducing government spending, as many of these people don’t contribute back to society and plan to live off benefit payments.<p>That being said, the U.S.’s indiscriminate belligerence toward everyone is making other nations wary. More people from the U.S. travel to the rest of the world than the other way around. If Europe and Asia start imposing travel bans in retaliation, it would make the world segregated again, benefiting no one.
