For such a smart guy, Larry missed the elephant in the room. This bill, like the 1986 amnesty, guarantees citizenship but does not have teeth to stop more illegal immigration. When Rubio et. al. confirm to all the world's poor that every person who can live here illegally will eventually become a US citizen, don't you suppose illegal immigration will increase even further than now? Whether they cross the border in the night or simply stay after their visa expires, they will eventually become US citizens. Plus their spouses, children, perhaps even their parents and siblings.
This is not pro-growth, this is national suicide.
