The new book "Immigration: A U.S. History" by Dina and Tan Bo has inspected the experience of immigrants from all over the world to the United States from all over the world，and the attitude of the US government and citizens to immigrants。The book takes immigration laws Bet365 app download and policies as a framework，Comprehensive consideration of the source of immigration and the economic status of the receiving country and the personal factors of immigration，Exploring the key topics of American immigration research，Including the background and motivation of immigrants、Settlement mode、Work、Family、racism and nativeism (nativism), etc.。Analysis results show，There are some repeated themes in the history of American immigration，For example, the long -term obsession of the "race"、Definition of "race"、The response of whites born in the country responded to the "new comer" to national policies and the lasting effects of public life。

 

two scholars said，The United States is known for "the country of immigration"，But this is not a formal or official naming，Instead, the progressist concept of some American people。but but，Even those who support immigrants most think，It should only receive a specific type of、Immigration that meets the specific standards they set。This Bet365 app download idea is contrary to the development of history。The United States urgently needs immigrants for most of the historical time，If there is no immigration，The United States will not form。

 

From the 18th century to the present，The main source of the United States immigrants changes from time to time，But the immigration population has the same characteristics: young、willing to adventure、Seeking more opportunities and better living conditions。Natural disasters have always been the driver of immigration。Looking at history，Local famine is one of the main reasons for immigrants。1845-1852，The main food crops of the Irish people in the potato infected with a large number of epidemic diseases，Continuous apology，Treatment of the Great Famine of Ireland。Escape，Many people immigrate overseas。1845-1855，More than 1.5 million adults and children from Ireland to North America。1960s，Famine occurred in the east of Germany Federation to today's Lithuania，A Bet365 app download large population immigrate to the United States。The 1970s and 1980s, the vine fungus infection in northern Italy, the first wave of Italians immigrated to the United States。Similarly，In the 21st century, many people immigrated to abroad to avoid the impact of climate change。but but，The degree of environmental threats today is unprecedented，And global。

 

Dina and Tan Bo talk about，American welcomes and exclude immigrants，Both praise and abuse。If immigrants can grow or weaken the United States、Immigration Makes the United States rich or poverty，It has always been a hot issue in American society。The relationship between Americans and immigrants has never deviated from politics，Immigration law in any historical period is political。but but，The political nature of the past immigration problem is far from being stronger as it is now。Current，A new phenomenon is，For the complexity of how to deal with the issue of immigration，American views are increasingly party -oriented。

 

History，The Republican Bet365 app download and Democratic Party have always claimed to restrict immigration and those who advocate "hug" immigrants，Can't say which party is an anti -immigrant or pro -immigration。But，"9 · 11" incident has a major change in this situation，Republican and Democratic Party tend to polarize the issue of immigration and internal homogeneity。Republican Party enthusiastically supports localism and anti -immigrant politics，Those who support immigrants within the party are like "silence"; the Democratic Party supports the protection of immigration rights and strongly opposes the demons of immigrants，Although there are many opinions in the party in the party receiving and border policies。

 

From Dina and Tan Bo's view，Both parties in the United States need to return to reason，The complexity of recognition of immigration issues，and realize that immigrants have made great contributions to the US economy，instead of consuming national wealth。History indication，The period when the most bet365 live casino games immigrants are often the strongest period of economic productivity。On the one hand，Immigrants do work that Americans born in the country are unwilling to do; on the other hand，They have set up many small companies，Each company hires employees、Early income。At the same time，Production of immigrants、Business、Consumption activities have also increased the tax income of the US government。
