Washington is finally going to start reimbursing hospitals for a small percentage of the costs of providing emergency care for illegal aliens. This is in addition to a Justice Department program that reimburses states and localities for a small share of the costs of incarcerating criminal aliens — a program the White House has twice unsuccessfully tried to eliminate. Maybe if the feds are forced to bear enough of the costs of illegal immigration, they might have an incentive to reduce those costs through immigration enforcement. Then again, maybe not.
