Funny that the US isn't the only country with border problems. Id say most western countries have immigration issues and most for purely economic reasons. 
We've been having an immigration issue, it's that each administration plays "hands off" and then "hands it off" to the next administration to "deal with it" (aka make promises).
Basically, now you have people who have been here for yrs, and flaunt it.
What is also happening, is that businesses use the guise of "helping people": everything is optioned for Spanish language, and they even write signs or paperwork in Spanish, and they say "Yes we speak Spanish", but all they want is their money, they could care in helping them. And the end result is that you have people who now think they are entitled to be catered to, while many are not legal. And then you have enclaves of people who have segregated themselves from "The Americans", they only deal with us when they need to or want to.
Sadly, big business and the politicians have created a Monster that they begrudgingly have to feed or deal with. And the fact is, it's not just Latinos, but Africans, Euros, Asians, Middle Easterners, are collectively doing the same thing.
When you get hit by a drunken driver, and then it's found out that the person does not have a license, but is illegal, and has been doing this for awhile. It hurts doubly. Because who is going to pay for the accident, the insurance, and sometimes the perp doesn't even do jail time---he/she flees.
You can't stop a person from "owning" a car. And that is something that I have seen almost all illegal immigrants do, regardless of nationality.
It only needs somebody from the top to either get hurt or a family member to get hurt for things to happen. And I'm waiting for it---America is a very "reactive" country, it has a history of waitig things to go very bad, instead of preventing it, before doing somethig about it.
