I'm certainly no economist (although I had a couple of classes in college with some really great professors) and I've never met the author, Dr. Samuel Addy; but I find his study interesting on a couple of levels. His report found that 40,000 to 80,000 workers earning between $15,000 to $35,000 annually have left the state and that the state's total goods and services produced will drop between $2.3 billion to $10.8 billion and the state will lose between $56 to $264 million in state income and sales tax collections.
Hmmm, that's a gap of 40, 000 workers, a gap of $8.5 billion (with a B!) in goods and services, and a gap of $208 million in sales tax collections...I know this, I would've received a very bad grade for predictions that swung to these extremes.
But, after working through some numbers on my own I decided to provide my version of the Cost-Benefit Analysis of the New Alabama Immigration Law, depicted in the chart below. Again, I'm not an economist or a scientist, I'm just a retired Marine who continues to use common sense.
