illegal immigrants are more likely to come from a socioeconomic disadvantage. what benefit do you gain from raising tuition to a price you know that they cannot pay?
this is like asking why we don't tax poor people more since a they make up a larger portion of the population and thus use the most resources provided by the govt
they can't afford it.
You are missing the entire point. They are illegals dude. They shouldn't be paying anything because they're illegally in the US. They should be deported.
