Excellent comments and insight!
This President stands up for America better than any in recent memory "over there." It's here that worries me.
As others have pointed out. We have laws.
I would urge we demand that Congress provide an ironclad guarantee that they'd force the executive branch to enforce any new laws! Better, give ordinary citizens standing, I believe it's called, so we could use the courts to protect Our Nation of Laws.
IMO the problem is the pro-"cheap" labor, anti-nation of laws crowd. The greed-related thinking impaired. Even if they were exempted from business-killing regulations and taxes they'd still hire "cheap" labor.
Waving flags they send Americans off to risk life and limb defending them and theirs. Waving job applications of ILLEGAL aliens-cum-guest workers they send those very same Americans returning from battle off somewhere else to look for work.
The business and private interests who do this are useful idiots.
But why does President Bush do it? The President is truthful when he says it's NOT amnesty.
I sincerely believe as stated above that this is part of globalization. Mirgrant labor (a developing country's economic diaspora) is as much a part of globalization as "free trade" transfer of wealth to developing countries. The mainline of both Parties want it.
