So you missed these lines from the post?
"It is difficult to determine the exact cost or contribution of unauthorized immigrants because they are harder to survey, but the study suggests they likely have a more positive effect than their legal counterparts because they are, on average, younger and do not qualify for public benefits."
"Undocumented immigrants pay an estimated $11.6 billion a year in taxes, according to the Institute on Taxation & Economic Policy. Immigrants are also less likely to take public benefits than the native-born population for two reasons. First, to receive most public benefits under the social safety net, immigrants must be lawful permanent residents for at least five years. There are approximately 9 million immigrants that fit that definition in the U.S. Of those, many would not qualify for welfare or other programs because their incomes are too high."
Not to mention that nearly every statement in the post about "immigrants" in general applied just as much or more so to illegal immigrants. The post specifically address that in those two sections, but you ignored that and didn't even make an argument for why your distinction invalidated those specific points.
