$520 billion over a SEVENTY YEAR (1937-2003)period is a DROP IN THE BUCKET compared to what it cost to house, educate, and for law enforcement associated for all those millions of illegal immigrants!!!
Not to mention costs from gangs like MS13, Russian mafia, etc.
If we need more 'low income workers', boost the temp worker program, but CHECK THE incoming people very thoroughly for disease and alterior motives.
We cannot afford to become a Latin-American style socialized revolutionary government.
Chump change came to mind and thanks for doing the math. I knew someone on the thread would beat me to the point, seeing as I was a late arrival.
