But even if you accept his data, he hasn't accounted for the productive value of immigrant labor. The companies they work for pay taxes and generate income beyond their own.
If illegal immigrants really had a negative impact on taxes and economy of a city why don't you see any mayors trying to get rid of them.
Anyone who thinks that productive employees are a burden on the community doesn't understand economics.

Awww..too bad for you! Another post that you will ignore. Several communities in Iowa have enacted zoning laws to keep OUT meat packing plants who wanted to open.

So, yes...they turned down the lure of a couple hundred jobs, and instead concentrated their efforts on helping legitimate businesses.
In addition, we just had a local community pass a law banning chickens in town. Yes...that's right. Our wonderful "aliens" were raising chickens and slaughtering them in the front yard. The neighbors were a little peeved about rivers of blood running down the end of the driveway. Some cities don't go lightly into the third world.
You are on the WRONG side of this issue; both in terms of the popular opinion and basic logic. But it's never stopped you yet!
