I have a question about illegal immigration?

I went to visit my aunt down in southern California (we are African American) and she and other African Americans and a lot of other White people were talking about illegal immigration. They were not saying any racial slurs but most of them were talking about moving to another state like in the Northeast somewhere. I asked my Aunt why and she and the others said they were tired of the current situation. The whole time they were all complaining about how in other states the schools still had music, athletic, and drivers ed programs, but they did not in their schools because the school system had to cut those programs to pay for ESL teachers. ( what is that?) Also one of the white guys made a joke and everybody lauged except me because I did not get it. He said ''all the American citizens/taxpayers should move.'', then the guy standing next to him said '' Well then who will pay for all the programs the illegal immigrants need ?!'' I do not understand what they mean, I thought the federal government paid for all those programs not them. Were they talking about taxes paid to the county, state, or federal government? Can someone please explain?
