Honest immigration is a good thing, for oppressed, persecuted and poor people who want the opportunity to improve their lives,
If they understand that laws of the land it religion and its culture they are moving to, must have some benefit,
because these things have helped make the country a magnet to other people of the earth.
Conversely, so many Americans (who lost 2016) that call for open borders have locks on their houses and cars.
The rich ones have armed bodyguards while calling for gun control.
The spoiled young call for compassion for immigrants, but most have never ever bought a homeless US veteran a meal.
