If you believe our government statistics you are gullible.
Why do you think they never list food stamps, subsidized and free housing, welfare, free cell phones, free cars and all the other goodies being showered on illegals and non-productive citizens?
You know those costs are buried and nobody has the courage to even mention them.
Since 53% of our population (lot higher counting illegals) are currently on Medicaid, I would have to say that this CBO baseline on expected cost is too low on the Medicaid line.
