There was a significant immigration influx from Lebanon beginning in the early Sixties. Many of 'em wound up in the Dearborn area, as has been mentioned, but they also wormed their way downriver.
I remember my Dad (who was an appliance repairman) who worked downriver. He explained how most of these muzzies operated -
They basically scrimped and saved, living off of barely nothing, then when they had enough to buy a house, they'd pay cash for it. Then they'd whistle up the rest of their family from Muzzieland then they'd come over and the process would start all over again.
You can't go into a gas station or what is called a "party store" (beer, cigarettes, lottery, sometimes liquor, snacks, etc.) without seeing that the place is run by a muzzie - they are pretty much everywhere now.
I haven't been to Dearborn in 30 years and have no intention of ever going again. The place is a complete shithole.
