The dynamic idea is that immigration significantly increases the size of the U.S. labor force, and that more workers mean more growth.
The labor force has shrunk because there are no jobs, not because there is insufficient labor. If you bring in more labor competition, all you will do is lower the wages available for such jobs as exist, and enrich the employers at the workers' expense.
Sorry pal, more workers means even less opportunity for the Americans already unemployed. The last thing this country needs is more cheap labor undercutting the people who are already here and out of work.
We're all against you, Kudlow!
