Glad you mentioned Glenn Loury. I listen to his podcast weekly.
Fact is, decades ago, and I've documented articles showing this, jobs done by lowskilled/low wage workers...were black. Period.
And we talk about the foundation for black economics...I'm not condemning us all to the bottom of the stack, but some money is better than no money. Especially when we read about raids on fast food joints, temp agencies passing over black candidates, entire black unions crying foul in places like LA for being undercut by illegals, etc...the effect of illegal immigration directly affects us more since we make up more of the bottom.
There is an impact and since I know you haven't checked everything I referred to you, do that, and get back to me.
I've done way more reading on this than you have...and if you're not satisfied with what I've thrown at you thus far, considering you haven't even looked at it, do me the courtesy of taking what I've done seriously.
