Here is another angle.

If illegal immigrants are being educated in this country, then why aren't they taking their education back to the country they came from? If they actually learned anything, then it's bound to be valuable somewhere even if they can't work here.

This is the whole point of education visas for people who come in legally. It is an opportunity for people from disadvantaged countries with poor educational systems to advance their countries by being educated abroad, in the US for example. They return and advance socially and advance their country by the contributions they make. Education visas were never intended to be immigration programs.

And this should apply to illegal immigrants as well. If they manage to get educated, then this is all the more reason for them to be shipped back home. But at this point whether they are actually being educated is a really huge "if".
