I don’t think people really have any desire to seriously look at this issue, but instead to just repeat pre-conceived biases.
The border can always be made more secure. If secure is defined as “perfect security” then it’s an impossibility–nothing is perfectly secure. Whether it’s worth devoting resources to making the border more secure is a complex economic and political question.
FWIW, if you look at actual numbers the illegal immigrant population stabilized in the mid-2000s, before any of Obama’s policies went into effect. Some of that was because of the declining economy at the end of the 2000s, but historically it was (at least since the 70s) an unprecedented period in which it wasn’t really growing. Since then it’s dropped, in part due to Obama’s policies that have redefined who is an illegal immigrant, but also due to other factors. For one, before he was liberal on immigration Obama oversaw a pretty draconian deportation regime, and for two the border is much more watched and fenced than it ever was. A large portion of the border is now fenced in areas where crossing over is easy. What enhanced borer security has done is make getting into America from Mexico more expensive. It used to be as easy as having the willpower to go for a short walk in the desert to meet up with family in a car on the other side. Now most crossings will require a professional traffickers involvement, and they have had to adopt steadily more sophisticated and expensive techniques to make the crossings.
This means the cost for getting here goes up–and that has absolutely (based on the numbers) had an impact on the number of illegal immigrants from Mexico coming here. People who might consider immigrating illegally are going to look at it using the same cost-benefit logic anyone would when making an economic decision. At a high enough price, crossing may simply not be worth it, you’ll either not be able to come up with it before hand or you’ll be in debt servitude working it off for so long on the other side that for some it actually becomes preferable to just stay in Mexico.
Much more important than the security question is the question of what immigration policy should be. Should we have a quota? No quota? Higher quotas than we have now?
My opinion is that we need quotas, but at a higher level than current. Further, the quotas should give preferential treatment to the most skilled immigrants (they largely are already set up to do that, but the low limits on the quotas causes problems.) How high the quotas to be, I couldn’t say. But rather I think it’s good for population to increase and not stagnate. So we should promote immigration insomuch as it is necessary to see our population growth at the very least keep par. Past a certain point it isn’t beneficial to grow population, but it’s rarely beneficial to see large reductions in population.
The reason we need quotas, is unlike the uninformed opinions of people in this thread who think “more immigrants is awesome, let them all come!” I recognize the economic realities of 2015 America versus 1815 America. We have a social safety net in this country. For that reason, an increase in the poor population is not a great benefit to the country. Instead, we want an increase in the middle and upper class population numbers. The large a share of the total population made up of poor people, the harder it will be to finance the social safety net that we have for them. Further, we have a fairly spartan social safety net by OECD standards. If we want to increase it, it becomes much more difficult the higher the proportion of our population ends up being poor.
Poor immigrants face many problems in 2015 America that would not have existed in the past. There are many good paying jobs even in 1925 America where ability to speak English, having a high school or college degree didn’t matter. A lot of Italians who came over went right into the coal mines, only their kids and grandkids got around to fully integrating and moving into more comfortable professions. But there isn’t that “bridge occupation” anymore. Instead there are a lot of truly miserable low wage jobs that will not support an immigrant family establishing itself here. It’s almost impossible for an immigrant with no language skills making $8 an hour (many illegal farm workers reportedly make under $5/hr) to successfully raise a family of kids who will have good economic attainment.
So what you will see, and what you do see, is immigrants moving here who cannot support themselves and their families to a level required to achieve generational attainment. How can kids do good in school when they are living in a two bedroom house with 15 other people? When they have no where and no time to study, no one to interact with that speaks the majority language to help build their English speaking and reading skills outside of school hours, no one to help them with their homework because the homework is in English, no one to help them with their homework even if it was in Spanish because they have to work all the time, when you have this scenario you’re basically bringing people into the country who are set up to fail. At the end of the 20th and now the beginning of the 21st century being successful in the economy more and more requires foundations that are nigh-impossible for low education, low income workers to have–and this causes problems for their children. This is true of native born Americans who are part of generationally poor families. We haven’t fixed places like the “Great White Ghetto” of Appalachia, or the many African American low income neighborhoods that house generational poverty inside many cities. So the idea that people who actually are coming to America with less job skills and probably less education than these classes of our own poor being able to turn out okay is largely a fairy tale.
The late 19th and early 20th century was a unique time in which a lot of people of low means had an opportunity, by moving to the United States, to “jump up” in class–particularly to position their kids to succeed well beyond their own success. Current America is not that place. People who come over with education, some money, and strong family ties and work ethic not always seen in middle class white Americans will often exceed middle class Americans in attainment. Those are the immigrants we want as much of as we can possibly get. But immigrants with no ability to even come close to success in the 21st century job market are largely just setting up camp–camps that will breed generational poverty from which there is not going to be any easy exit. For that reason we need to be very concerned about the effects of unrestricted immigration of low education, low income persons.
But if we refuse to even try to regulate our borders, much of this is moot–because we don’t have an immigration policy then. Instead, it will be whoever from wherever that gets to decide these issues for us.
