If that chart is true, and I assume it is, I am not surprised - but it doesn’t address the point I was making.
You also mentioned that illegals gain access to welfare through their citizen children. How does that work? You mentioned the EITC, but they don't file. Let's say they have a four-year-old citizen child.
Finally, based upon your information, the two problems appear to be (a) ILLEGAL immigration, and (b) the absence of job growth in the economy. Your data only touches on the unemployment cost of illegal immigration. It does not include the economic costs of government services to them, or the social and criminal costs.
