My great grand parents were coal miners and were here legally. The mines sponsored them. They were not criminals, gang members, child traffickers, or here to sell fentanyl. Nor did they break in to apartment buildings with guns screaming we are Poles and you need to get out now or die. This is our building now. BIG DIFFERENCE. The mines gave them housing which rent was taken out of their pay.
When bodies were needed to secure the border and fuel economic growth, immigrants were welcome. Before overpopulation stressed resources and changed the atmosphere. Heck, before the USA was a nation, farmers would purchase slaves. They preferred Negros because the slaves could easily be identified. This forced migration has many similarities to slavery.
