Yeah Sure. Just like the employers of Illegals were prosecuted after the 1984 AmnestyNOT! If our Government AGAIN chooses to take the easy way out of not enforcing its immigration laws by Amnestying Illegal Aliens it will NEVER find the discipline of doing it AFTER an Amnesty. History is quite clear on this.
You are being disingenuous in your arguments, though I know its not the first time you have taken this tack. Your case for Amnesty reminds me of the old saw on the definition of Insanity as: "doing the same thing over and over again and expecting different results each time".
The idea of enforcing employer sanctions is a sound one that needs to be aggressively pursued.
As for a long-term solution to the illegal immigration issue, I don't see it happening on a "fortify the border" basis for the following reasons:
The best deterrent to illegal immigration is to make it worth the potential immigrant's while to stay in Mexico.
Unfortunately, I don't see that happening unless we invade Mexico and opt to either rule it as a conquered province for a couple decades or to simply replace the current government with one more aligned with our interests. The good news of this idea is that our southern land frontier would be greatly shortened. The bad news is that we'd damn near double our seaward frontier.
