I'm from all over. Born in Louisville. Grew up in Indiana. Also lived in Michigan, Tennessee, Florida, North Carolina, Alabama. Currently in Oklahoma.
The illegals have definitely depressed the areas whereof you (and I) speak. They have virtually destroyed north Tulsa as I'm sure they have St. Louis.
But the carnage in Kalifornia, particularly southern Kal is unbelievable.
They're destroying the infrastructure. Overwhelming social services like no place else. Completely shutting down emergency rooms because they selfishly insist upon using ERs as their primary care provider.
And, yes, in LA for example, a home will sell for twice what it sells for elsewhere. But the (prospective) seller is only rich on paper. The vast majority of them can't afford to move.
Yet thanks to the crimigrants, decent folk don't want to stay.
And, most importantly:
THEY TOOK OUR JOBS!!!!!
