Whilst I think that illegal immigrants can be problematic (certainly if they receive social benefits and/or don't pay tax), I can't be angry at them because I know what they do is often done out of desperation and the will to do anything for a better quality of life.
At the end of the day we all want to improve our quality of life, I can relate. But it just so happens that some of us were born on the side with the greener grass already.
As for jobs and social services, I can see the problem they pose to the system. For example if a state has to factor in bilingual education for the children of illegal immigrants, then the cost to educate students will sky rocket. If a person has been undercut in their job, then it will begin to cause many problems such as higher unemployment of legal citizens and unmonitored working conditions (which inevitably lead to poor working conditions) for illegal immigrants.
But again, I can't really be angry at these people in spite of this because I know that in many cases they illegally cross borders to increase their quality of life.
