9) End the INSANE Green Card Lottery.
This scam was initiated by Teddy Kennedy in 1965. Citizens in most countries can go to the US Embassy to throw their name in the hat and become the lucky winner of one American Green Card.
This even includes citizens in terrorist hellhole countries like Yemen. I once talked to a guy from Ireland who won one because his buddies egged him into applying as a BAR BET!
Conversely economically productive immigrants from India and Mexico are not eligible, due to the huge numbers coming from those countries. They go to the back of a ten-year line if they wish to come legally.
The Diversity Lottery Visas? Yeah, that is a particularly absurd category dreamed up by the loathsome Ted Kennedy.
But I think it was implemented with the Immigration Act of 1990, signed into law by the first Bush (so W was just carrying on the family tradition of being terrible on immigration). This bill further increased mass immigration that was reignited by the 1965 Hart-Cellar bill. Part of the way it did this was by giving out 50,000 of these ridiculous lottery visas each year.
