A little something is not better than what they pay now. Our tax system will still not support their use of our social programs. Just look at Los Angeles County. Their hospital system is being overrun by illegals who go there for basic care because they know they cannot be turned away. They carry no insurance and don't pay anything up front.
Even with California's relatively high taxes, they can't afford it.
The cost to keep them out and deport them is entirely justified.
