There are some important differences between the wave of European immigration to this country that occured between 1845-1925 and the situation today.
1. First of all, the question before us is ILLEGAL immigration. It has nothing to do with legal immigration.
2. The massive European immigration that previously occured was legal and regulated. I am assuming you have heard of Ellis Island.
3. No one ethnic/linguistic group dominated among the immigrants. There were literally millions of Germans, Irish, Poles, Russians, Greeks, Italians, Norwegians, etc.
4. Once the immigrants got here, for most there was no turning back.
5. There was no government attempt at promoting "multiculturalism"
6. The United States at that time was emerging as a world power and the country was rapidly undergoing industrialisation.
Today, the massive immigration is mostly illegal. We have no idea who is entering the country, or for what reason. The fact that this is still occuring almost 6 yrs after 9/11 is criminal.
The illegal immigrants are exploited by their fellow countrymen in trying to sneak across the border ( the coyotes), and are exploited in this country by unscrupulous employers who often do not pay minimum wage, benefits, etc.
The majority of illegal immigrants are Spanish speaking from Mexico and Central America. This is creating a parallel society in this country. Just look at other countries that are torn apart by language- Canada, Belguim, Spain, most Third World countries. The rise of bilingualism is undermining our society.
There are far fewer reasons to assimilate than in the past. The illegal immigrants can watch Spanish TV, listen to Spanish radio, shop and live in all Spanish speaking areas, get credit cards at Bank of America with no valid social security numbers, and travel frequently back to Mexico.
My family came to this country in the earlier wave of immigration. They came here legally. The government did not support them. There was no bilingual education. 3 out of my 4 grandparents were immigrants. One of my grandmothers never learned English. My father, although born here, could not speak English when he entered school. There were no bilingual Italian/English classes, so he had to learn English.
I am not opposed to legal immigration by Latinos or any other group, but the current situation is a disaster for this country, and our politicians of both parties have a lot to answer for. The current bill before Congress is a joke.
