Why Can't We Be More Like Alabama?

Or Mississippi?
You do not hear that very often.

To cope with illegal immigrants, the legal design Georgia has a better system than most of the states in the country. Alabama, Mississippi, South Carolina and Arizona all have the optimal structure. So why is that there are still so many illegal aliens in Georgia? The answer is contractors and business owners pay cash for day workers, and the there is a great deal of identity fraud.
Looking at the map above, found at NumbersUSA, what frightens me is how a state can actually pass legislation that prohibits E-Verify. Reasoned out this belies an intent to break federal law, and followed through makes these states, California and Illinois, guilty of conspiracy and subject to Racketeer Influenced and Corrupt Organizations Act, aka RICO.
