Like I said in other post, in-state tuition to the children of illegals is not the largest monetary issue for illegals.
But please do not ask for evidence for obvious things. No evidence is required for commonsense items. No evidence is needed to prove one looks for food when hungry. OK, may be some one is doing university level research to prove that, but you get my point.
Every benefit, large or small is a magnet for illegals. Including free maternity care, free emergency hospital care, free K-12 education for children of illegals, food stamps, and yes in-state tuition in university of Texas.
The biggest obstacle to stopping illegal immigration is the Federal Government. The states are limited by law and hampered by the Feds refusal to do their job. Again, Texas’s in-state tuition isn’t free, the parents pay taxes and pay for the tuition.
