1. legalize the illegals who are working jobs being paid underneath the table
2. They will become extremely low wage legal workers driving the cost of wages down
3. The border security will not happen, so new illegals will flood the beneath the table market.
4. All of these will vote socialist.
5. Eventually we will be a nation of serfs owned by a wealthy elite, a new aristocracy.
