Who pays healthcare for their children? Since they don't earn enough on paper to feed their many children most qualify for food stamps, WIC, TANF, section 8, and social welfare programs ad infinitum. Especially with the construction example, every American worker they've undercut now qualifies for all these programs as well. Do you see how this is twice as expensive to those who are still employed and paying the taxes which now barely pays the interest on the national debt?
What happens when these illegal immigrants are granted amnesty? Will they continue working at these sub minimum paid under the table jobs? No, they're going to move onto the social welfare rolls and be replaced by other illegal immigrants. They can still collect welfare while they work as long as they're paid under the table anyway so long as they don't earn too much to get the attention of the IRS. This works out good for wealthy businessmen who need the cheap labor. It's partly why the minimum wage laws are such a joke since none of this is enforced uniformly at all.
