These people are not stupid, they are traitors.
Immigration must serve the purpose of the Republic and its Citizens. The welfare of the immigrant is irrelevant.
These people bring nothing to the USA that we need. They are mostly illiterate, unskilled, and penniless. We have do not have full employment with industries crying out for more labor. We do not have frontiers that need populating.
What they actually doing is importing taxpayer subsidized labor, and a reliable voting bloc to disenfranchise American citizens.
This is no different from the Roman patricians importing cheap barbarian labor and will end the same way the destruction of the nation.
Why don’t they at least work to expand legal immigration? Why focus on illegals?
