This is about "why"? The Immigration Crises. Yes, we have had a flood of immigrants before..
When? From 1890 to 1924. Where from? Ireland, Russia, Poland, Ukraine, China, etc, etc. You name it, and that is where they came from. Why?..lots of reasons: 1. religious freedom, 2. economic advancement, 3. economic opportunity 4. desire to start a new life in a "free country" 4. ease of entrance 5. possibility of getting education. 6. friends and relatives did it urged them to come too 7. sections of cities were welcoming areas where their language was spoken and their churches were..
..How did they enter? The immigrants stayed at Ellis Island for a week to prove that they did not have tuberculosis and they had to be able to read a language, (any language) That is it. Industry was growing everywhere and we needed cheap labor. It was in the country's best interest to have these people.
(all four of my grandparents came in 1910 from Russia what is now Ukraine.)
...Why did it change? After World War One, there was a need to blame someone for the horrific deaths that were reported and that countries experienced. The immigrants were blamed. They were an easy target, even though the U.S. deaths in WWI were minor compared to other countries. The Russian Revolution created fear, and competition for jobs was strong. Immigrants worked for less, so the cost of labor was low. People who were here before were angry with the immigrants. They spoke a different language, they lived in their own neighborhoods, they often went to private schools, had churches etc.etc.etc. So as a result of these reasons and others not mentioned, the immigration act of 1924 was passed through Congress and became law. After 1924, the law created quotas for certain countries to allow their citizens to enter and stay here. So therefore, so many thousands could come from Ireland, Russia, Mexico, China etc. Systems were set up to control the numbers, where there were few in the first 20 years of the 1900s. There was also anti immigrant "hate" for lots of reasons.
So why are these people coming here? Same as before, to start a new life, and give opportunity to their children. Getting in was relatively easy. You come in for a short time, yes visitors are allowed in, of course, and you stay. period. So what is new? This administration is rounding them up, (those that are here beyond their times or came in illegally) and throwing their children into these detention centers. That is new.
Before Trump, we let them stay, some got thrown out, most stayed in illegally. The new children were citizens because they were born here and life went on. The kids melted in because they spoke almost perfect English because they spoke it at school and learned it. Life went on for better or worse.
Now, we round them up, and basically throw the kids in jail. So..who decided to do this?...It was President Trump who decided to change the way we treated these people. Why? "Got to get rid of them you know" says his supporters. And Drump says the same thing. Throw the kids in jail. The immigration and border patrol catch them and basically do that (with orders from Drump) Kids are suppurated from parents. (says Trump) That is it and that is all of it.
