Half of all U.S. adults believe mass immigration from poor, violent Third World countries has driven up crime rates while hurting the economy, according to a bilingual survey conducted by Pew Research Center.

Fifty years after the U.S. passed the Immigration and Nationality Act of 1965, which all but eliminated immigration from America’s traditional European stock and culture in favor of migrants from the Third World, Americans and descendants of recent immigrants aren’t pleased with the results.

Nearly half of all respondents (49 percent) want current immigration levels to be decreased. Currently the U.S. government voluntarily imports 1.05 million foreigners on green cards alone each year. Green card holders will outnumber the populations of Iowa, New Hampshire, and South Carolina combined within only ten years if existing levels of immigration are allowed, a prospect which alarms some Americans concerned about highly unnatural and extreme population increases. Pew asked respondents to which word comes to mind when they think of immigrants:

When asked what one word first comes to mind when thinking about immigrants in the U.S. today, the word “illegal” is offered by 12 percent of American adults—more than any other word. Other respondents offered words such as “overpopulation” (5 percent), “legality” (4 percent), “jobs” (3 percent), “deportation” (3 percent) and “work ethic” (3 percent).

Noticeably absent are the supposed virtues of immigration touted by the elite: “diversity,” “enrichment,” “vibrancy.” In Chapter Four of its report under the heading, “Relatively Little Knowledge About U.S. Immigration Facts,” Pew snootily reports “35 percent of Americans say that the U.S. foreign-born share is actually higher [than 13 percent, or 41.45 million foreigners]: 28 percent say about four-in-ten Americans are foreign-born, and seven percent say that more than half of the U.S. population is foreign born.” Maybe Pew stumbled on Americans who lived in historically black neighborhoods which became entirely Hispanic almost overnight.

These results are unsurprising, considering:

1) media members and law enforcement work furiously to cover up mass immigration’s destabilizing effect on every aspect of American life,

2) the government does not keep track of any immigrant crime statistics, and

3) when a flood washes away your home, you don’t spend time counting out individual droplets that wiped out the foundation.

The 28 percent of respondents who said four-in-ten Americans are foreign-born are on the mark. By 2060, one-fifth of all Americans will be foreign-born, and only non-Hispanic, native-born whites will suffer a population decline, a decline of 16 million in a mere 45 years — in a country founded by George Washington and built by European settlers and pioneers. In less than 100 years after the government took steps that could destroy its traditional demography, Hispanics will be 29 percent of the population, numbering over 110 million.

That prospect doesn’t excite all Hispanics, however: 20 percent of them told Pew that immigrants make America worse off. As Breitbart News previously reported, current policies admitting huge numbers of immigrants “continues unaltered at a time when automation is reducing hiring, and when a record share of our own workers here in America are not employed,” a terrible deal for everyone living here except Democrats and the super-rich:

Respondents sense that taking in tens of millions of immigrants from countries such as Mexico is making America less safe, especially for women and children cherished by America’s historic Anglo-Saxon culture. Breitbart News has exposed many, many crimes committed by immigrants that the media did its best to cover up. While the murder of Kathryn Steinle, allegedly at the hands of a five-times deported Mexican illegal alien, elicited nationwide outrage (and a blank stare from the Obama administration), other crimes are buried. For example:

A Republican party that promised to crack down on crime and curb immigration would thrill and motivate its base. The Pew survey shows how at odds the GOP establishment is with its base on immigration.

In 2013, establishment darling Sen. Marco Rubio, still pushing to hand out U.S. citizenship like candy, then pushed the Gang of Eight bill, which would have ramped up the green card giveaway to 30 million in only ten years, tripling already unpopular levels of immigration. But 67 percent of Republicans want immigration levels decreased — and don’t want their children to live in a poorer and more dangerous country where foreigners and their descendants, who have no affection for or attachment to traditional America, account for 88 percent of population growth within only 50 years. Control of the economy and government will by then be neatly transferred into the hands of an imported population if Republicans spit on or ignore their base.
