This is a legit good question, someone who walks across the border is extremely unlikely to be able to afford cancer treatment. There’s a near infinite supply of needy people in the world. What is the legitimate, rational argument for allowing them all to come here and receive aid and treatment? Even if you decide you’re not going to “allow” it, if the incentives still exist, like California’s free healthcare for illegal immigrants, they will still come because the benefits are worth the risk.
